Mix it all up. If you choose to use extra lean ground beef, you’ll want to add about 2 tablespoons of fresh bread crumbs to the mix. The best method is in a big bowl, digging in with your hands getting them nice and dirty. If you’re afraid of gunk, throwing it all in a gallon Ziplock bag and mashing it through the protective plastic works and keeps you safe from amoebas.
Mash out (or roll out) the well-mixed beef mixture into a rectangle a little bit larger than the size and shape of that 12-pack of rolls. They will be pretty thin and don’t be surprised if they aren’t as “firm” as the burgers you usually make. Blame the egg for it, but note that they’ll cook up perfectly fine.
Chop it up into 12 small burgers, and throw it on the grill for about 3 minutes on each side. They don’t take long, and try not to move them until it’s time to flip! With these burgers, you don’t even need any fix-ins, they’ll be nice and juicy and already seasoned, but some grilled onions go nicely with it if you must.
