To each pound 90/10 ground beef, add a quarter cup finely diced onion, two minced cloves garlic, a tablespoon of salt, two of coarsely-ground black pepper and three of Worcestershire sauce. Form into patties, brush with light vegetable oil and refrigerate for at least an hour. Grill until just done; they should be pink in the middle. Top with smoked cheddar before serving.
