Yes, I know you already know how to grill a burger. You may want to try this out though...not much work and makes them more juicy and flavorful.
Ok, make a slice of toast. Remove from toaster and let it cool down to room temperature again. Drop it into a blender or food processer and destroy it into a powder. Dump that into a large mixing bowl.
Add a teaspoon each of: salt, pepper, garlic powder, cornmeal
Add 1/2 teaspoon each of: cumin, ginger
Mince an onion finely and toss in.
Crack an egg in there too.
Add a tablespoon of Worcestershire if you have it.
Now mix it all up well, and then add in 2 lbs of ground beef. Using your hands (nothing else will really do it) combine the whole mess and make your patties.
