Broiled Sweet-and-Spicy Salmon with Pineapple

Heat broiler, with rack in top position. Cook rice according to package instructions. Meanwhile, in a small bowl, stir together maple syrup and cayenne pepper. Season salmon with salt and pepper. Spray a rimmed baking sheet with cooking spray, arrange salmon and pineapple in a single layer, and brush with half the maple syrup glaze. Broil until salmon is cooked through, 8 to 11 minutes, brushing salmon and pineapple with glaze halfway through. Cut pineapple into chunks. Add cilantro to rice and fluff with a fork. Serve rice with salmon, pineapple, and lime wedges, if desired.
