Preheat oven to 425℉. Line a rimmed baking tray with aluminum foil and lightly spray with nonstick spray.
Add the salmon pieces, olive oil, brown sugar, paprika, garlic powder, onion powder, salt and pepper to a bowl. Stir gently to completely coat the salmon with the spices.
Spread the salmon bites onto the foil lined tray so they are evenly spaced out. Place the salmon in the oven to bake for 8 minutes.
While the salmon is baking mix the bang bang sauce ingredients in a small bowl.
When the salmon has cooked for 8 minutes it will be mostly cooked through. Turn the oven to the broiler setting and place the salmon on the top rack position. Broil for 2 minutes to crisp the salmon.
Serve the salmon with bang bang sauce as an appetizer or serve with rice and a cucumber salad to make salmon bowls.
