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

Form the mixture into 4 equal patties.

Drizzle olive oil on both sides of the patties.

Preheat the grill to medium-high heat.

Place the patties on the grill and cook for about 6-7 minutes on each side, or until the internal temperature reaches 165°F (75°C).

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

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

Spread mayonnaise on the bottom half of each bun.

Place the grilled chicken patty on top, followed by lettuce, tomato, and pickles.

Top with ketchup if desired and cover with the top half of the bun.
