You’re going to love this pesto chicken sandwich. Sourdough, toasted in olive oil and topped with grilled chicken, pesto, Swiss cheese, and fresh tomatoes. A perfect easy and attractive dinner for guests or a cozy night in.
You’ve got bright and salty pesto slathered over toasty sourdough and piled high with perfectly grilled chicken, Swiss cheese, and tomatoes. Pretty much all the best things in life in one delicious sandwich. This is one of my favorite dinners for guests, because it’s fantastically easy, looks beautiful, and tastes so darn good. It’s also generously sized, so no one’s leaving the table hungry, and it’s a perfect way to use up extra pesto you have sitting around your kitchen! Feed guests good food to bursting AND use up leftovers? Who’s the host with the most now?
Sprinkle both sides of your flattened chicken breasts with Italian seasoning, salt, and pepper.
Heat an electric counter-top grill or large skillet over medium-high heat. If using a skillet, spray with cooking spray or coat with a little olive oil. Cook chicken breasts for 5 to 8 minutes per side, until an instant-read thermometer inserted into the centers of the breasts reads 165°F. Transfer chicken to a cutting board and allow to rest for 5 minutes before slicing into 1/2-inch wide strips. Wipe out your pan.
Assemble sandwiches by spreading mayonnaise (if desired) and about a tablespoon of pesto over the bread. Top with chicken, tomatoes, and cheese, and brush tops and bottoms of the sandwiches lightly with olive oil or a thin layer of mayonnaise to help them brown.
Cook sandwiches over medium to medium high heat until first side is toasted and flip. The sandwiches are done when both sides are golden and the cheese is melted. If making in a skillet, you will probably only be able to fit two sandwiches at a time in the pan. Place cooked sandwiches on a plate in a warm oven while you repeat the process with the last two sandwiches to keep them warm.
