Deli sliced pepperoni (try to get the size that is about 2 1/2 inches across and ask for them to slice it thin but not shaved)
Vegies of your choice like onion, mushroom, and/or peppers
Meat of your choice (optional since you already have the pepperoni, but bacon is yummy)
Cheese (mozzerella is best)
Tomato sauce (see recipe)
Recipe
Using your small muffin tin, line the cups with the pepperoni as if they were paper muffin cups (no need to grease the pan)
Spoon in 1/2 teaspoon of tomato sauce
Add finely chopped veggies of your choice, maybe a teaspoon in each cup
Grate cheese and pack it on top or easier, cube cheese and put 3 cubes in each cup
Bake in 350 degree oven for about 15 - 20 minutes. Check periodically so they don't burn
Remove from oven and let sit for about 5-10 minutes before running knife around edge to loosen
Remove from pan. They should hold their cup shape and contain everything inside.
