Lay the slices of garlic toast out on a baking sheet. Spread a spoonful of sauce over each slice.
Sprinkle each slice with cheese, then top with pepperoni slices or desired toppings.
Bake at 400 degrees for 5-6 minutes until cheese is melted. If you like your cheese extra melty, you can then broil the pizzas for a minute or two. Serves 4.
