To make this recipe, begin by spraying a cooking sheet with non-stick spray and place your English muffin halves in the oven while it's preheating to 400 degrees; this will keep your mini pizzas from getting soggy by toasting them a little. While the oven is preheating, chop the bell pepper and grab the rest of your ingredients.
Once the oven is close to 400, carefully remove the English muffins (don't burn yourself!). If you're having kids help, you can either pre-toast and cool the sliced English muffins or skip the step. The toasting does help the muffins not to become soggy with sauce.
Add one to two tablespoons of tomato sauce per muffin, a generous sprinkling of mozzarella cheese, and whatever ingredients you wish to add for your pizzas.
Bake for about 8 minutes at 400 degrees or until the cheese is melted.
