Grease a 9x13 baking pan and place diced chicken at the bottom. In a small bowl, mix mayonnaise (or yogurt), Parmesan cheese, seasoned salt, pepper, garlic, and red pepper flakes.
Spread the mixture over the chicken, sprinkle with breadcrumbs. Bake at 375°F for 30-35 minutes until chicken is cooked. Serve over pasta, rice, or on its own using a slotted spoon. Enjoy!
