When I made this I made one pepperoni pizza for my husband using a tomato sauce, pepperoni, onion and cheese. You can always use half the dough and make one pizza(or two smaller ones) and store the remaining dough in the fridge as long as you use it within a few days. Or you could make a smaller version of the focaccia in the original recipe to use for sandwiches as it's very good that way too. Or you could also cook the crust as in the first part of the recipe and then cool it completely and freeze it to use the next time you want pizza. If you do only end up making half, make sure to half the toppings in the recipe.
