Ingredients
Instructions
- Step 1
Place the boneless skinless chicken breast on a cutting board. Using a sharp chef’s knife, cut in half horizontally to create two thin sliced pieces. Next, cover the chicken loosely with plastic wrap and use a meat tenderizer or rolling pin to pound the chicken, until both pieces are tenderized and thinned out to about 1/2 an inch or so. Season both sides of each piece of chicken liberally with salt and pepper. Set aside on a plate while you prepare the pesto mayo and buns.
- Step 2
In a small bowl, mix the mayonnaise with teaspoon or so of pesto mayo until well mixed. Cut your buns in half (or use your favorite bread – sourdough would be great too) and toast both sides to your liking.
- Step 3
Heat oil in a large nonstick skillet or saute pan over medium-high heat. When hot, add the raw chicken to the pan using tongs. Cook until browned, about 3-4 minutes, then flip. Cook for another 2 minutes, then reduce heat to low. Add sliced mozzarella cheese, then cover the pan and cook for another 2-3 minutes until the chicken is cooked through and the cheese is melted. Check to ensure the chicken has reached 165F, then remove from heat. Add a spoonful of remaining pesto to each chicken breast, then cover lid with a lid to rest briefly while you prepare the buns.
- Step 4
Slather the pesto mayo on your buns, then add a pesto mozzarella covered chicken breast to each bun. Add a slice of tomato or two and place bun on top. Serve with fries or potato wedges and a side salad!
- Step 5
Save any remaining cooked chicken (without pesto if possible) in an airtight container for up to 4 days. Reheat on the stovetop in the same way it was cooked, or in the air fryer for 4-6 minutes at 350F.
