I made my basic pizza dough crust and pre-baked it for 8 minutes in a 450 degree oven. Then, I added one can of refried beans, then put the seasoned taco meat on top, some cheese, and stuck it back in the oven for a few more minutes. Then, I set out toppings on the kitchen counter (lettuce, salsa, sour cream, and crushed taco chips). Everyone got to add their own toppings to their pizza, just like they would to a taco.
I'll definitely make this again.
