Brown the ground beef over a medium high heat. Once browned, add the spices, salt, pepper and water. Simmer until the ground beef is at your desired level of sauciness.
While the ground beef simmers, you make the microwave tacos. A 1/4 cup of cheese is enough for two tacos. Divide the 1/4 cup into two thin rounds and put in the microwave for approximately 45 - 60 seconds (This will vary with different microwaves).
Once they feel crispy to the touch, carefully lift them from the plate and drape them over the side of a baking tray until cooled.
Once you've made 8 shells, fill with the toppings and enjoy!
