Mix all the dry ingredients into the meat with a fork or your hands.
Form a ball with the meat mixture. Score it into quarters with the side of your hand. Form patties.
Cook on a hot grill or in a hot cast iron frying pan. Flip the burgers only once when you begin to see blood on the top of the meat. Add cheese to melt.
Serve on a roll with lettuce, onion and guacamole.
