1 ½ lb salmon
1 medium onion, quartered
1 ½ tablespoons butter, chopped into a few pieces
Preheat oven to 375 degrees. In a large sheet of foil, arrange half of the onion (separate it into pieces). Place salmon on top of the onions, top with butter, the rest of the onions and sprinkle with salt and fresh ground pepper. Fold foil over the salmon and pinch close. Bake for 30 minutes or until salmon is cooked through.
