Begin by preheating your oven to 400°F. Place the focaccia bread in the oven for about 8 minutes. This helps amplify its flavor while ensuring a warm, crisp texture.
If you have an air fryer, cook the chicken at 400°F for 10-12 minutes, flipping halfway through. Don’t have an air fryer? No problem! Cook it on a stovetop over medium heat for about 5 minutes per side. Once cooked, slice the chicken into thin, even strips.
Spread about ¼ cup of pesto sauce evenly over the bottom half of the toasted focaccia. Layer on the sliced chicken, mozzarella, and roasted red peppers. Add the top half of the focaccia bread to complete the sandwich.
To finish, place the sandwich back in the oven for an additional 2 minutes. This step warms the components and melts the mozzarella to gooey perfection.
Remove from the oven, slice in half, and serve immediately. Pair it with a fresh green salad for a well-rounded meal.
