Instead of buying frozen pizzas, make your dough from scratch. A plain bread dough can be made in advance and frozen. A paste can be made with fresh or canned tomatoes & tomato paste mixed together. Top with your favorite topping and your expense should be somewhere in the neighborhood of $2.00. It can be a lot more fun to really creative with toppings, like for example have a member of the family get to choose all the toppings, which you can rotate who gets to pick each time. Also, you can have more than one person make the pizza like the kds or spouse- even invited guests!
