Combine the meat, egg, bread crumbs, garlic, parsley, salt, pepper, and onion powder in a large bowl.
Mix well then divide into four equal portions and shape into 1/2 inch thick patties with dampened hands.
Add the oil to a large pan over medium heat then add the patties and cook on each side for about 4 minutes or until cooked through (internal temperature of 160F).
Serve on buns with your choice of toppings.
Notes:
Dampen your hands with cold water before shaping the patties to stop them from sticking to your hands.
