Preheat the oven to 375F.
Trim any excess fat from the chicken breasts and then lay them flat in a single layer in a baking dish.
Sprinkle the taco seasoning evenly over the chicken breasts then pour the salsa over the top of the dish and cover with cheese.
Bake on the middle rack in the oven for 35-45 minutes or until the chicken is cooked through and the juices run clear.
Serve hot over rice, greens, cauliflower rice, tortillas, or potatoes. Garnish with fresh cilantro and sour cream for an extra delicious touch!
