Tortellini Emilia

Walnuts, Gruyere, and prosciutto turn this pasta dish into a company special entree.

Ingredients
2  8-ounce package dried cheese-filled tortellini
3  tablespoons finely chopped red onion
2  tablespoons finely chopped shallots
1  tablespoon margarine or butter
2  cups half-and-half or light cream
1/2  cup milk
2   egg yolks
1/4  cup grated Parmesan cheese
1  tablespoon  snipped fresh sage or 1 teaspoon dried sage, crushed
1/2  cup shredded Gruyere or Swiss cheese (2 oz.)
1/2  cup walnut pieces
2  ounces prosciutto, finely snipped, or cooked ham, finely chopped 

Directions 
Preheat oven to 400 degree F. Prepare tortellini according to package directions. Drain; set aside. In a medium saucepan cook onion and shallots in hot margarine over medium heat until tender. Stir in cream and milk. Bring just to boiling. Remove from heat.
In a small bowl lightly beat egg yolks. Slowly add about 1 cup of hot mixture to yolks, beating until combined. Return all to saucepan. Cook and stir over medium-low heat about 10 minutes or until slightly thickened and just bubbly. Stir in Parmesan, sage, and 1/4 teaspoon pepper. 

Transfer half of the tortellini to a 2-quart rectangular baking dish. Sprinkle with the cheese. Pour half of the sauce over tortellini. Top with remaining pasta, the walnuts, the prosciutto, and remaining sauce. Bake, uncovered, for 20 minutes or until top is lightly browned and mixture is bubbly. Let stand 10 minutes. Makes 8 servings.
