Pesto Chicken Caprese Sandwich

1 . Stage

Preheat the oven to 375 degrees C (190 degrees C).

2 . Stage

Thinly slice chicken breasts in half and season with Italian seasoning and salt. Place chicken on a rimmed baking sheet.

3 . Stage

Bake in the preheated oven until chicken is no longer pink in the center and the juices run clear, about 20 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).

4 . Stage

Cut heirloom tomato and mozzarella cheese into four 1/3-inch thick slices. Set out tomato slices on a baking sheet and top with mozzarella slices. Add to oven and bake for the last 10 minutes with the chicken. Remove chicken from oven.

5 . Stage

Turn oven to broil and broil tomatoes and cheese, until cheese has melted, 2 to 3 minutes. If desired, add ciabatta buns and toast under the broiler until browned, 1 to 2 minutes.

6 . Stage

To assemble the sandwiches, place a chicken filet onto the ciabatta bun, top with tomato and melted mozzarella, and 1 tablespoon pesto.
