Brown the beef and add salt, pepper and cayenne pepper.
Add the onions and garlic and sauté until onions are translucent.
Add the rest of the ingredients—-except the cheese— and let cook on medium for about a half hour until the hash browns are soft.
Then reduce heat to medium low and add the gruyere cheese and cook until it melts. Pay attention and stir frequently after you add the cheese because the it will stick to the bottom and burn if you leave it too hot for too long.
Serve with Cholula hot sauce and Fritos and enjoy your cheeseburger soup.
