In the 80's my mom used to make us tortilla pizzas. She would put milk on the tortilla then all the pizza stuff in the oven for a few. Turns out good and not costly! And so from the 80's! When I dated a lady with 5 kids I told her how to make them it blew her kids minds at the time. https://www.allrecipes.com/recipe/258013/easy-tortilla-pizza
