Finely mince the onion and garlic. Place the ground burger in a bowl with the onion, garlic, Worcestershire sauce, salt, and pepper. Use your hands to mix everything together. It's important to mix the seasonings with the burger thoroughly.

To form the burgers, split the mixture into fourths and use your hands to make patties. Let the patties rest for five minutes for the flavors to absorb into the burgers.

Grill the burgers on a medium hot grill for five minutes, flip and cook for another five to six minutes or until the burgers have the desired level of doneness.
