Put all ingredients in large bowl, or food processor bowl.
Whip until mixture turns pasty and strings form, 30-60 seconds in a food processor, 3-5 minutes by hand.
Form mixture, with a bowl of warm water at hand for sticky fingers. Make patties or mold mixture onto skewers. If it’s too soft and falls off the skewers or patties don’t hold their shape, refrigerate for an hour. The recipe can be made to this point and held refrigerated for up to three days.
Cook like a hamburger. Grill, broil, or panfry until finished, 8-15 minutes, depending on heat source and intensity. (USDA suggests ground beef should reach 160F for safety. I usually break one open to check.)
Serve on pita, salad, or rice, perhaps with a dab of Greek yogurt.
