Grilled Pesto Chicken Sandwiches

Considering that I was obsessed with roasted red peppers for the first few years of learning to cook, I can hardly believe that I have included just one lonely recipe that uses them as an ingredient since starting this blog.  In fact, obsessed might be an understatement here– it was extremely rare that I ever made a dish without them.
Grilled Chicken Pesto Sandwiches
It all started in college, when I had just started dating James.  Only a few months before, I randomly decided– as I often do– to master a new hobby, as drawing, painting, writing, altering clothes, kickboxing, web designing, and playing the piano were beginning to bore me.  (That’s not to say I abandoned any of these hobbies entirely, but I just needed to move on to learn something new.  I’m a restless skill-hoarder.  It makes it impossible for me to balance my efforts because I’ll decide important things such as functioning like a normal human being are less urgent than becoming, say, the ultimate master champion of ukulele playing, and nothing can possibly take a wink of time or attention away from that goal.)

Ingredients for the best chicken marinade ever.
The hobby I decided to pick up was cooking, and I quickly spiraled into “nothing matters besides making delicious food” mode.  I constantly had people over for dinner, and my boyfriend was lucky enough to be my taste-tester every single day, often more than one meal a day.  For unknown reasons, I refused to cook any protein that wasn’t poultry or seafood at the time, but since James is a fishophobe, chicken was on the menu every night.

“Chicken, you say?  I thought this was about roasted red peppers?”  It is.  You see, while there are thousands of creative ways to cook chicken, I believe that people who are learning to cook tend to go through flavor eras.  Just like Picasso had his Blue Period, I had a Mediterranean Period.  Every single chicken dish I made included at least 3 of the following ingredients:
Garlic, mozzarella, feta, roasted red peppers, pesto, olive oil, balsamic vinegar, and/or spinach.  That’s it.  That was my whole cooking repertoire for at least 6 months.  And I should clarify that the roasted red peppers were never the ingredient to be left out.

James never complained, (mainly because he loves those flavors just as much as I do,) and he still gets excited every time I tell him I’m making something with roasted red peppers.  I should clarify, though, that I was able to come up with some pretty awesome and surprisingly diverse meals using those main ingredients (hello, Pasta Greco) which is why it’s absolutely ridiculous that only one of them is on this blog so far!  Well, now it’s two, I suppose.  I had to end this appalling injustice before it got out even more out of hand.
Grilled Pesto Chicken Sandwiches
Here’s the breakdown for these sandwiches:  you make the best simple marinade ever created for chicken, let it sit overnight, and then grill it up.  Chop it, and pile it on fresh Italian bread with a liberal amount of pesto, mozzarella, roasted red peppers, and tomatoes.  Bring it back to the grill and toast both sides until the mozzarella begins to melt and the bread is nice and crispy.  Ta-da!  If you don’t have a grill, don’t worry.  You can make these in a frying pan or in the oven and they still taste delicious.

These sandwiches are great for every occasion.  The thick grilled bread helps them travel well for picnics, tailgates, and outdoor events without becoming soggy, and the ingredients all taste wonderful whether they’re hot, cold, or room temperature.  I’ve never met a person who didn’t like them, and they fly off of the serving tray when I make them for get-togethers.  Best of all, they’re simple to make, so whether you want to whip one up for yourself, a few for your family, or dozens for a big party you’re hosting, these are stress-free and foolproof!

If you’re looking at the picture above and thinking, “Oh no!  I don’t own one of those cast iron grill press things, so I can’t make this!”  don’t worry.  If you don’t have one, just press down on the top of the sandwich with a spatula to force the sandwich ingredients together as they cook.  Either way works perfectly fine!

Summery pesto, flavorful grilled chicken, roasted red peppers, gooey mozzarella, and fresh Italian bread make this grilled sandwich a hit with everyone!
For the marinade:
  • 1½ tablespoons balsamic vinegar
  • 1 teaspoon dried thyme
  • 1 teaspoon dried oregano
  • 1 tablespoon Dijon mustard
  • 2 teaspoons garlic powder
  • ¼ cup extra virgin olive oil
  • Kosher salt & ground pepper, to taste
For the sandwiches:
  • 4 boneless, skinless chicken breasts
  • 1 loaf fresh Italian bread
  • 6 oz fresh mozzarella cheese, sliced thick
  • 1 cup pesto
  • 1 tomato, sliced
  • 1 12oz jar roasted red peppers, drained and cut into pieces
  1. Combine all of the marinade ingredients in a large freezer bag or large container. Add in the chicken breasts and let them marinate in the refrigerator overnight, or at least 4 hours.
  2. Cook the chicken on a high heat grill for about 5 minutes per side or in an oven set to 375 for 15 minutes.
  3. Chop up the chicken into bite sized pieces and set aside.
  4. Slice the Italian bread and smear pesto liberally on each slice. Layer on the roasted red peppers, grilled chicken, mozzarella, and a slice or two of tomato. Top with another slice of bread, pesto side down.
  5. Put the sandwiches back on the hot grill or on a tray in the oven, and weigh them down slightly so the ingredients combine. You can do this by using a spatula or cast iron grill press on the grill, or by placing another, greased baking sheet on top of the sandwiches in the oven.
  6. Flip halfway through to toast each side of the sandwich, and remove from heat once the cheese has begun to melt and the bread has gotten crisp. Serve hot, cold, or at room temperature.

    these look great they sort of remind me of the flatbreads you made over the summer when we lived together

      Haha, yes! I’m telling you, I really just made everything with those same ingredients. I’m glad I’ve branched out now, but man, you just can’t go wrong with those flavors…

    These are fantastic! I made them a few weeks ago for the family,and they loved them. So much so that I’m making them again tonight. Thanks for the recipe.

    Argghh, If I see another amateur cook blog blabbering on about her life interspersed with ten photos of the food she is making I will go mad. Give us the ******* recipe at the top of the page and shut up already!

      If you don’t like the way I format my blog, you’re welcome to find your recipes elsewhere. Or make them up yourself and write your own blog, since you seem to have it all figured out. The point of a blog is to do all of the things you’ve mentioned you don’t like, so maybe or a cook book would be more up your alley.

    Just the idea I was having a hard time coming up with! This will be served at my book club meeting on Sunday. Thank you for the inspiration.
