There are really no set ingredients for this recipe. This time she used pepperoni and mozzarella, but Suzi likes to substitute spinach as a vegetarian alternative. You can use any variety of veggies including broccoli, artichokes, asparagus, and zucchini. Mozzarella’s a given, but you could mix in fresh parmesan or ricotta. Besides pepperoni, you can try Canadian bacon, ham, or Italian sausage. Watch the video, then get the recipe for Suzi's Potluck Pepperoni Bread.
