Baked Pineapple Salmon

Preheat oven to 350°. Line a large rimmed baking sheet with foil and grease with cooking spray. In the center of the foil, lay pineapple slices in an even layer. Season both sides of the salmon with salt and pepper and place on top of pineapple slices. In a small bowl, whisk together butter, chili sauce, cilantro, garlic, ginger, sesame oil, and red pepper flakes. Brush all over salmon fillet. Bake until the salmon is cooked through, about 25 minutes. Switch the oven to broil, and broil for 2 minutes, or until fish is slightly golden. Garnish with sesame seeds and green onions and serve with lime wedges.
