In a large frying pan, brown the ground beef over a medium high heat.
Once browned, add the taco seasoning and water. Lower the heat and allow to simmer until the ground beef is at your desired level of sauciness.
In another frying pan over medium high heat, take a handful of cheese and make a small thin circle. Allow to cook until slightly crispy on the bottom then carefully scoop up and drape over a baking dish until cooled.
Once you've made 8 shells, fill with the ground beef and toppings then serve.
