What you need:
Regular sized tortillas
Other toppings as desired
An open can (pizza sauce), or biscuit cutter to make the right size tortillas.
Preheat oven 425 degrees and spray the cupcake tin with non-stick spray.
Take a tortilla and on a flat surface cut circles a little bit larger than the size of the cupcake molds. If you use the pizza sauce can, you should be able to get the right size. I used a drinking glass to make an indent in the tortilla and then a knife to cut it since I didn't have an empty can.
Take each tortilla and push it into the cupcake mold.
Add a spoonful of pizza sauce, or in my case pasta sauce, since I didn't have pizza sauce. Cover with cheese and other toppings.
Bake for 12-15 minutes or until cheese had melted and the tortilla is golden brown.
I think the cup I used may have been a little too small. It was only slightly larger than the cupcake mold. If the tortilla is bigger, it should make a cup like a tortilla shell for a Mexican salad.
