I usually make Turkey Tetrazzini for New Years Day.

Turkey Tetrazzini Recipe
Ingredients
12 oz egg noodles, spaghetti, linguini or other pasta
12 ounces mushrooms, sliced (about 4-5 cups)
1/2 cup unsalted butter
1/4 cup all-purpose flour
1 1/2 cups of milk
1/4 cup cream
2 cups chicken broth
1/4 cup dry sherry, vermouth, or dry white wine
3 cups coarsely chopped cooked turkey
1 cup cooked peas
2/3 cup freshly grated Parmesan
1/3 cup shredded Swiss cheese
1/3 cup fine fresh bread crumbs
Salt and Pepper

1 Cook the pasta according to the package directions, al dente; drain well and set aside. After you've started with the pasta, proceed to the next steps.
2 Preheat oven to 375°F.
3 Cook the mushrooms in 3 Tbsp of the butter over moderate heat, stirring, until all of the liquid they give off has evaporated, about 10 minutes. Set aside.
4 In a large, heavy saucepan, melt 1/4 cup of butter. Stir in the flour, and cook the mixture over low heat, stirring, for 3 minutes.
5 Gradually stir in the milk, cream, broth, and the wine or sherry. Bring to a simmer and cook over medium-low heat, stirring constantly, for about 5 minutes.
6 In a large bowl combine well the pasta, the sauce, the mushrooms, the turkey, the peas, and salt and pepper to taste. Stir in 1/3 cup of the Parmesan and the 1/3 cup of Swiss cheese, and transfer the mixture to a buttered shallow 3-quart casserole.
7 In a small bowl combine well the remaining 1/3 cup Parmesan, the bread crumbs, and salt and pepper to taste, sprinkle the mixture evenly over the Tetrazzini, and dot the top with the remaining 1 tablespoon butter, cut into bits.
8 Bake the Tetrazzini in the middle rack of the oven for 30 to 40 minutes, or until it is bubbling and the top is golden

Oh I have the best recipe for leftover turkey. It's one of Giada's recipes:

Turkey Bolognese

1/3 cup extra-virgin olive oil
2 onions, chopped
6 garlic cloves, minced
2 celery stalks, finely chopped
1 large carrot, peeled and finely chopped
1 ½ pounds coarsely shredded cooked turkey (preferably dark meat)
6 cups marinara sauce (she suggest her recipe but I used jarred Bertolli Organic)
1 cup water
2/3 cup chopped fresh basil
Salt and freshly ground black pepper
1 ½ pounds spaghetti
Freshly grated Parmesan cheese

Heat the oil in a large, heavy pot over medium heat. Add the onions and garlic and sauté until translucent, about 8 minutes. Add the celery and carrot, and sauté until the vegetables are tender, about 8 minutes. Add the turkey and sauté 1 minute. Add the marinara sauce and water. Bring the sauce to a simmer over medium-high heat, then decrease the heat to medium-low and simmer gently for 25 minutes, stirring often, to all the flavors to blend. Stir in the basil. Season the sauce generously to taste with salt and pepper.

Meanwhile in a very large pot of boiling salted water, cook the spaghetti, stirring often to prevent the pasta from sticking together, until tender but still firm to the bite, about 8 minutes, Drain, reserving one cup of the cooking liquid. Add the pasta to the sauce and toss to coat, add enough of the reserved liquid to moisten as needed. Serve with the Parmesan.

This is DELICIOUS!

This the recipe or currently used at the Camberley Brown Hotel in Louisville, Kentucky.

Ingredients:

Instructions:

In a large saucepan over medium heat, melt butter. Gradually add flour, stirring constantly, until smooth and free from lumps. Gradually stir in milk until sauce comes to a gentle boil, stirring constantly; remove from heat. Add Parmesan cheese and stir until melted and well blended.

In a small bowl, beat egg. Gradually add 1 cup of hot sauce, 1/3 cup at a time, to the egg, stirring constantly. Gradually add egg mixture to remaining sauce, stirring constantly until well blended; add salt and pepper to taste. Fold in whipped cream.

For each Hot Brown sandwich, place two slices of toasted bread on a metal (or flameproof) dish. Cover the toast with a liberal amount of turkey. Pour a generous amount of sauce over the turkey. Sprinkle with additional Parmesan cheese. Place entire dish under a broiler until the sauce is speckled brown and bubbly. Remove from broiler, sprinkle with diced pimientos, cross two pieces of bacon over the top, and serve immediately.
