Combine egg, onion, garlic, pine nuts, lemon juice, salt, pepper and spices in a medium bowl.  Stir well to combine.  Crumble in ground beef and combine all ingredients together until all is evenly incorporated.  Form into 4 patties.  Grill over medium heat (350-400 degrees) 12 - 15 minutes on the first side, flip and grill an additional 8-10 minutes or until the internal temperature reaches 165 degrees.

Serve with desired condiments - pita bread, hummus, cucumber yogurt dressing, lettuce, and/or tomatoes.
