You will need:
Pizza Crust (buy one, make one, whatever --just make sure it's a deep dish style one)
1 can refried beans (or make them, your call)
Grated cheese (moz, jack, cheddar) (enough to cover the pizza all over 1/3 of an inch thick at least --maybe two and a half cups for a medium pizza)
sliced and chopped lettuce (2 cups or so --medium sized bowl)
sliced tomatoes (two tomatoes or 1 cup)
diced onion (1/4 to 1/2 cup, depending on how much you like onions --get the white ones though!)
Dorito's Nacho Cheeze chips. (1 bag)
1/4 pound ground beef for medium pizza
optional: Spicy Jack cheeze
some small amount of corn-meal to sprinkle on cooking sheet
Spread the refried beans onto the pizza crust like you would pizza sauce. Make sure it's about 1/4 inch thick everywhere.
Sprinkle some of your onions on top.
Add cheeze to taste, sprinkling remainder of onions into the cheeze.
Roll beef into little balls, no bigger than 1/2 inch in size and place on top of cheeze. If you want to pre-cook these, that's a good idea too.
Put the whole works into the pre-heated oven for about 12-15 minutes at 425 degrees. If you like corn meal, sprinkle a light dusting onto your cooking sheet before placing the pizza on it.
Pizza is done, when cheeze is well melted and beef is cooked and brown. Depending on your oven, you might have better luck pre-cooking the beef or just skipping it.
Remove cooked pizza from oven and cut it to your preference.
Sprinkle sliced and chopped lettuce on top, followed by about 1/2 cup crused Doritos. Finish with chopped tomatoes on top and it's all ready to eat.
Enjoy a very good Taco Style Pizza!
