Start by grabbing a large mixing bowl. Add in your ground chicken, breadcrumbs, mayo, egg, garlic powder, onion powder, salt, and pepper. Use clean hands or a spoon to gently combine everything until well mixed. Don’t overwork it—just until the mixture sticks together.
Once your mixture is ready, divide it into 4 equal portions. Shape each one into a patty, about the size of your burger buns. Place them on a plate and set aside while you heat your skillet. If you have time, chilling them for 10 minutes helps them firm up.
Heat olive oil in a non-stick skillet over medium heat. Once hot, place the patties in the pan. Cook each side for about 5 to 6 minutes until they’re golden brown and the internal temperature reaches 165°F. Avoid flipping too early or they may fall apart.
While the burgers are cooking, mix up your bang bang sauce. In a small bowl, combine the mayo, sweet chili sauce, sriracha, and honey. Stir it well until it's completely smooth. Taste and adjust the spice level to your liking.
Toast your buns in a dry skillet or in the oven until lightly golden. Place lettuce on the bottom bun, then the chicken patty, followed by a generous spoonful of bang bang sauce. Add tomato if you like, then top with the other half of the bun.
