1. Preheat the grill to high heat, approximately 450°F to 500°F.
2. In a large mixing bowl, combine the extra lean ground beef, minced garlic, American mustard, olive oil, Worcestershire sauce, and salt.
3. Once mixed, separate the mixture into 4 even sections.
4. Once separated, shape the sections into 4 round patties.
5. Once you have your patties formed, grease your preheated grill.
6. Cook the patties for 7 to 9 minutes, flipping them once during that time.
7. Once the patties are cooked, remove them from the grill and start assembling your burgers with the buns, lettuce, tomato, onion, pickles, and ketchup.
8. Once your burger is made, dig in!
