It's so easy. I buy the pizza kits at Costco- they are not refrigerated- you get 4 pizzas, and 4 packets of sauce. If you don't have those, any standard prep for a pizza will do.
I sauteed a large pack of Costco organic ground beef last night, with taco seasoning (because we had tacos last night). I saved about a cup of meat. I sprinkled that over the pizza. I also sprinkled over it 3 eggs, which had been scrambled well, with taco seasoning. Then I topped the whole thing with about 1/4 cup of Trader Joe's Mexican blend cheese. After the cheese was melted and the crust was browned, I served each slice with a dollop of guacamole and a spoonful of salsa.
