Set up a steam bath. I used a stock pot and filled it with water to around 1/2 - 3/4 full. Place steamer basket/steamer on top of the stock pot or other pot you choose to use. Bring water to the boil on med high heat.
Make a mixture in a small dish of your salt, pepper and garlic powder
Add salt, pepper, and garlic powder mix to your ground chuck. Lightly mix this with your hands. (Don't over do it! Just mix enough to incorporate the seasoning into the ground chuck).
Form 3 equal sized patties (approximately 1/3 pound each). Place these into the steam bath once the water is boiling). Cover, and steam for around 8 minutes.
Uncover and check after 8 minutes (they should be done!) and add 1 slice of cheddar to each hamburger patty). Let each cheddar slice melt (will take around 30 seconds or so) and once melted you are ready to add each patty to your hamburger buns.
Enjoy these moist and juicy cheeseburgers with your condiments of choice! Some great options are pickles, onions, mustard, ketchup and mayo!
