Preheat oven to 350 F/ 175 C
Open muffins in half and lay on a parchment lined baking sheet.
Spread ½ - 2 tablespoons sauce over each muffin half.
Add 1 tablespoon cheese to each.
Add any toppings you prefer.
Top with the other 1 tablespoon cheese.
Bake in oven for about 10-12 minutes, watching as you go and taking out when just beginning to brown. If you like them crispier then bake until browning on top.
