Boil pasta. I use whatever pasta I have left. Sometimes I combine different types.
Cut pepperoni up into quarters.
Grate fresh cheese. I've used cheddar, mozzerella, pepper jack, colby jack, etc. use what you like.
Cut up veggies.
Combine cooked pasta, pepperoni, cheese, and veggies into 9x13 greased pan. Put foil over top and bake for about 20 to 30 minutes at 325.
Serve with garlic bread.
