A community for discussion about burgers. Share recipes, photos, or questions about burgers. A burger is a sandwich which consists of two buns and a ground patty of protein, most commonly beef. A chicken sandwich does not qualify as a burger unless the patty is ground up and not a whole filet of grilled or fried chicken, or pulled BBQ chicken.
