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

Divide the mixture into 4 equal portions and shape them into patties.

Preheat the grill to medium-high heat.

Cook the chicken patties on the grill 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 until golden brown.

Spread mayonnaise on the bottom half of each bun, then layer with lettuce, tomato, pickles, and the cooked chicken patty.

Top with the other half of the bun and serve immediately.
