In a large bowl, combine ground chicken, panko breadcrumbs, green onions, egg, garlic powder, onion powder, salt, and black pepper. Mix until well combined.
Form the mixture into small patties, about 2-3 inches in diameter. You should get about 12 patties.
Heat a large skillet over medium heat and add a tablespoon of oil. Once hot, add the chicken patties in batches, cooking for about 4-5 minutes on each side or until golden brown and fully cooked through.
While the patties are cooking, prepare the bang bang sauce by mixing mayonnaise, sweet chili sauce, and sriracha in a small bowl. Adjust the sriracha to your preferred spice level.
Once the patties are cooked, assemble the sliders by placing a chicken patty on each slider bun. Top with a generous dollop of the bang bang sauce, a lettuce leaf, and pickles if desired.
Serve immediately and enjoy your Bang Bang Chicken Sliders!
