at least 3 lbs ground beef
Soy Sauce
Garlic Powder
Ground Black Pepper
1 Egg

Note:  If less that 3 lbs of ground beef is used, omit the the egg and add a small amount of soy sauce or the beef will be runny.

Put ground beef in mixing bowl and add egg.
Pour soy sauce over meat  (approx 1/8 cup for 2 lbs meat).    
Sprinkle garlic powder over meat (enough to very lightly cover the top of the meat).
Sprinkle pepper over meat (again, use a light covering, add more if desired).
Mix thoroughly.
Make patties and grill.

For added flavor:
Grill onion slices on grill rack to add to hamburger.

Place cheese on the patties during the last couple of minutes of cooking.  Some cheese suggestions are:  provolone, mozzarella, cheddar, and of course American.

Add grilled bacon to hamburger (grilling bacon tastes much better than fried bacon and does not have the grease that fried bacon has).
