4 boneless skinless chicken breasts
2 tablespoons olive oil
2 tablespoons taco seasoning
1 1/2 bell peppers, thinly sliced
1 small red onion, thinly sliced
1/2 cup shredded Mexican cheese
Cilantro, chopped, for serving
Preheat oven to 450°F and grease a baking dish with nonstick spray.
Make horizontal slices across each chicken breast, stopping 1/4-inch from the bottom.
Coat chicken with olive oil and rub taco seasoning into the meat.
Tuck peppers and onion into each slice then place chicken in prepared baking dish.
Bake for 15 minutes, remove, top with cheese, and return to oven until cheese has melted and chicken has cooked through, about 5 more minutes.
