Prepare the Salmon: Pat the salmon cubes dry with a paper towel. Season with salt, pepper, garlic powder, paprika, and cayenne pepper if using.
Dredging Station: In three separate bowls, place flour in one, beaten eggs in the second, and panko breadcrumbs in the third.
Coat the Salmon: Dip each salmon piece into the flour, then into the beaten eggs, and finally coat evenly with panko breadcrumbs. Press gently to adhere the coating.
Fry Until Golden: Heat about 1 inch of oil in a large skillet over medium-high heat. Once hot, fry the salmon bites for 2-3 minutes per side until golden brown and crispy. Remove and drain on a paper towel-lined plate.
Make the Bang Bang Sauce: In a small bowl, whisk together mayonnaise, sweet chili sauce, honey, Sriracha, and lime juice.
Toss and Serve: Drizzle or toss the crispy salmon bites in the bang bang sauce. Serve immediately and enjoy!
