I let my kids make little individual pizzas using hamburger buns or small sub buns. I have even used this method for sleepovers & my Camp Fire Club. Kids LOVE making their own dinner - could set out salad fixin's too, for kids to make a salad while their waiting for the pizzas to "bake".

buns (about 2 per child)
pizza sauce
grated Pizza cheese (I like the Kraft 4-cheese blend, but could use plain
mozzarella)
pepperoni, italian sausage, diced or sliced ham, mushrooms, whatever you like

Set all ingredients out in bowls and let kids build their own pizzas. Adult places them in toaster oven and toasts till cheese is melted. Adult should remove pizzas and serve.
