Remove skin from salmon. Slice each asparagus in half and blanch in microwave or on stove until partially cooked. Arrange on the bottom fillet: onion, asparagus, lemon. Place second fillet on top, then tie up securely like a roast. Place salmon and marinade in a baking dish for 30 minutes to one hour, turning once or twice to evenly coat. Depending on size of fillets, bake for 30-40 minutes in oven at 350 degrees or BBQ on the grill. Garnish with lemon slices and dill.
