* In a small saucepan over medium heat, melt 1/4 cup butter or margarine. Add 1 cup sliced mushrooms, 1/2 teaspoon beef bouillon granules, 1/3 teaspoon dried dill weed and a dash of pepper; sauté for 2 minutes or until mushrooms are browned and bouillon is dissolved. Stir in 1/4 cup dairy sour cream and just heat through. Remove from heat, cover and keep warm while preparing omelets. Spoon over omelets and garnish with parsley sprigs.
