In a mixing bowl, combine ground chicken, garlic powder, onion powder, salt, and black pepper. Mix until well combined.

Form the mixture into 4 equal patties.

Preheat the grill to medium-high heat and brush with olive oil.

Place the patties on the grill and cook for about 5 minutes on each side, or until the internal temperature reaches 165?F (75?C).

If using cheese, add a slice on each patty during the last minute of cooking to melt.

Toast the burger buns on the grill for 1-2 minutes.

Place the cooked patties on the bottom half of each bun, top with lettuce, tomato, and mayonnaise, then cover with the top half of the bun.
