We had an EMS cookout and grilled up a bunch of burgers that were 85% ground chuck. Seasoned up the meat with salt n' pepper and some minced onions. Had plenty of mushrooms, caramelized onions, Swiss and sharp chedders slices, dill pickle slices, ketchup, mustard, mayonnaise, and Miracle Whip (for those who like it), tomatoes and lettuce. And for buns we used grilled cheese sandwiches...! One for the top bun and one for the bottom bun. It was a flippin' feast and those folks got their grub on...!
BTW, a really good sauce for burgers is made by mixing Tabasco Chipotle Sauce and mayonnaise.
When I make em' at home, I like to use big, freshly baked rolls from the bakery (cut em' in half with a bread knife) for the buns.
