Preheat the oven to 325 degrees. Butter 2 pieces of foil or parchment paper and set aside. Season salmon with salt and pepper. Saute the vegetables in the butter for 2 to 3 minutes just until they begin to get tender. Add the cream and cook until most of it has been absorbed by the vegetables; season with salt and pepper. Place each salmon fillet on the piece of buttered parchment or foil and top with cooked vegetables. Seal the salmon and place the pouch on a baking sheet. Bake for 10 minutes. Remove the pouches from the oven transfer the salmon, vegetables and their juices to a heated plate. Serve as is just with French bread or with a side dish of cucumber curls and mint.
