Incredible burgers

2 lbs of ground beef
1 large onion diced
1 tsp Salt
1 tsp Pepper
1 tsp Garlic powder
1 package of sesame seed hamburger rolls

12 slices of each; aged Swiss cheese, mild cheddar, Monterey Jack cheese.

Mix all the ingredients with the ground beef, and grill to your taste. Add 1 piece of each cheese to the burgers.

Brush rolls with butter and grill till toasted.

Putting the burgers together is fun; first add mayo, lettuce, and tomato to the top bun. Put the cheeseburger on the bottom bun and put it together.
