I make pepperoni pizza and often have leftover pepperoni and bottled spaghetti sauce (that's what I use as pizza sauce. I like Prego traditional best!) This is a great way to use the extra stuff. We all love these!
Mozzarella and/or Cheddar Cheese
Pepperoni (you can use canadian bacon or sausage if you like that better)
Heat pepperoni til sizzling. Set aside. Place tortilla in skillet, add cheese and pepperoni and fold over. Cook til cheese melts. Dip in pizza or spaghetti sauce.
You could get fancy and use leftover roasted veggies, too!
