recipe here, and I followed it pretty closely. Here's what you do.
24 oz marinara sauce
51 turkey pepperoni
4 c mozzarella cheese
Preheat oven to 350. Put a little sauce in the bottom of a greased 9x13 pan. Place a little sauce, 4 pepperonis, and some cheese in the center of each tortilla, then roll them up and place them seam side down in the pan. Top with more sauce, cheese, and the remainder of the pepperoni. Bake for 25 minutes. Serve.
Like I said, super easy, and you can mess with the ingredients/pizza toppings however you like.
