1. To cook fresh asparagus, wash and scrape off scales. Break off and discard woody bases of asparagus. Cut asparagus into 1-1/2-inch pieces. In a covered saucepan cook asparagus in a small amount of boiling water for 4 to 8 minutes or until crisp-tender. (For frozen asparagus or broccoli, cook according to package directions; drain and set aside.)
2. In a large skillet cook turkey, onion, and sweet pepper until vegetables are just tender and no pink remains in turkey. Remove from heat; drain. Set aside. Grease a 3-quart rectangular baking dish. Arrange meat mixture in dish; top with cooked asparagus.
3. In a large mixing bowl combine eggs, milk, flour, Parmesan cheese, lemon-pepper seasoning, and tarragon; beat until smooth with a wire whisk or rotary beater. (Or, combine these ingredients in a blender container; cover and blend for 20 seconds.)* Pour egg mixture evenly over layers in baking dish.
4. Bake in a 425 degree F oven about 20 minutes or until a knife inserted near the center comes out clean. Sprinkle with the Swiss cheese; bake 3 to 5 minutes more or until the cheese is melted. Makes 6 servings.
