  1. Preheat a greased grill to medium heat.

  3. Cook onion on grill until they are softened and browned, stirring often, about 10 minutes.
    Set onions aside while you grill the beef patties.
  4. Cook beef patties until charred and fully cooked through, about 4-5 minutes per side.
    Adjust grill temperature as needed. Internal temperature should register 160°F on an

aluminum foil.
● No need to thaw beef patties before cooking.
