It's absolutely delicious when it's hot and bubbly, but still amazing 30 minutes later (unlike some appetizers). I like to spread it on Carr's Table Water Crackers. It's also great on bread.
I tore the recipe for Pepperoni Pizza Spread out of Taste of Home magazine years ago. But as I've mentioned many times, I am incapable of following a recipe as written. Here's my version:
Pepperoni Pizza Spread
2 c. mozarella cheese, shredded 6 oz. black olives, sliced
1 1/2 c. colby-jack cheese, shredded 1 small green bell pepper, chopped
3/4 c. mayonnaise 3 mushrooms, chopped
about 15 pepperonis, chopped
Combine ingredients in a large bowl and mix thoroughly. Transfer to a 1.5 quart baking dish. Bake uncovered at 350° for about 25 minutes. The edges will be lightly browned and bubbly. Serve with crackers or bread.
