For a spicier kick, use a hot barbecue sauce or add a pinch of red pepper flakes to the chicken while cooking. Feel free to customize your pizza with other toppings, such as diced bell peppers, onions, or jalapeños. If you don't have taco seasoning, you can substitute with a mixture of chili powder, cumin, garlic powder, and onion powder. For a crispier cornbread crust, bake it directly on a baking sheet lined with parchment paper instead of in a baking pan.
