Found this recipe in Fish & Seafood Recipes and tweeked it a little. I know there are other ones on the site, but I put it in my recipes so I wouldn't lose it. I used 2 (10 x 10-inch) sheets of aluminum foil.
Preheat oven to 375 degrees. Turn up edges of 1 sheet of foil so juices will not run out. Place slamon in the center of foil. Sprinkle with salt, lemon pepper and garlic powder. Place dill and lemon slices on top of salmon. Pour vermouth evenly over fish.
Cover fish with second sheet of foil. Crimp edges of foil together to seal packet, leaving head space for heat circulation. Place packet on baking sheet. Bake 20-25 minutes or until salmon flakes easily when tested with fork.
