Here is a yummy but easy recipe for Chicken Tetrazini that I got from my Mom; I have no idea where she got it. It should be straight forward to substitute turkey for chicken, although you might have trouble finding a four pound turkey. ;-)
Chicken Tetrazini
1 4 lb stewing chicken in parts
1 tsp salt
1/2 tsp ground white pepper
1/2 tsp dried rosemary
1/2 lb egg noodles
1/4 c butter
1 large onion, chopped
1 green pepper, chopped
1/2 lb mushrooms, sliced
1/2 c heavy cream
1 1/2 c grated Parmesan cheese
1/4 c minced Italian parsley
Put chicken in pot with salt and cold water to cover. Bring to a boil, remove any scum that forms, and add white pepper and rosemary. Simmer, covered, for 2 1/2 hours, until chicken slips off bone.
Drain water into large saucepan and add water to make two quarts. Boil and cook noodles; drain.
Bone and skin chicken, cut meat into small pieces. Melt butter in large skillet. Saute onion and pepper for 5 minutes; add mushrooms and cook 5 more minutes. Add cream, chicken, noodles, 1 cup of cheese. Mix and heat; top with remaining cheese. Makes 4-6 servings.
