Preheat oven to 400F.
Pour a tbsp of Olive oil on a Flatout flatbread and spread around. I used way too much in this picture so don't go according to this picture
Spread sauce onto the flatbread. My wife likes to rub a garlic clove over the flatbread, instead of sauce. Spread within about a half inch from the edge of the flatbread so you have a little crust.
Sprinkle on a cup of mozzarella cheese. Don't forget, you can also add toppings like chicken, tomato, onions, hamburger, pepperoni, or whatever you'd like. I just don't have that stuff right now.
Put your pizza in the oven at 400° for 6ish minutes depending upon how you like your pizza cooked. Yes, my pizza is directly on the rack because I have no pots or pans as I'm moving this week.
Here's the finished product. I burned mine a little bit because I forgot about it. It cooked for approximately 7 minutes, so 6 minutes would work better.
Following are pics of some of the pizzas I've made. They're fun to make, low-calorie, and cheap. The flatbreads are 80 cal each, and the cheese is as much as you want it to be.
