Place a flour tortilla on an oiled cookie sheet. Add a couple of tbsp. of salsa for Mexican Pizza or spaghetti sauce for Italian pizza. Spread the sauce nearly to the edge of the tortilla. Sprinkle about 2 to 3 tbsp. of cheddar or mozzarella cheese on top and add the olive oil. Then bake in a preheated oven until the cheese begins to turn golden. Remove and place on a plate before cutting with a pizza wheel.
