Chicken Pesto Sandwiches

I marinate chicken breasts in pesto for at least an hour. When ready, add olive oil to your pan. Get the BEST pan HERE. Add your chicken breasts and cook until done. Take a ciabatta roll and spread a mixture of mayo and pesto to both sides. Add fresh mozzarella and cook for 5-7 minutes. When that is done, Assemble your sandwich. I cut my chicken breast into slices, add salted tomatoes, and spinach.
