The hamburgers turned out amazing, so I wanted to share the recipe:
4lbs of thawed ground beef/chuck
1-2cups marinade, ours is similar to bbq sauce
a generous dash of tony's seasoning, and garlic salt
a little more than half a sleeve of Ritz crackers (these make a perfect substitute for bread crumbs)
Mix everything together and form into patties, I think this made about 12.
A good friend getting her hands dirty, so I could deal with other things (or because I get grossed out by mushing a bunch of raw meat)
Throw 'em on the grill till they're just the way you like!
