Smoked Turkey Tetrazzini

Every year Alan gets a turkey from work, but we eat at my mom's so we save his. Since his favorite hobby is BBQ/smoking meat lately he did the turkey this way for us to have. After several turkey sandwiches, I must do something else with the meat because I'm tired of them!
Here is a yummy recipe from Southern Living that we enjoy.

1 12oz. package of Fettuccine, cooked and drained
1/4 c. butter
1 medium onion, chopped
3 T. flour
1 t. salt
1 t. fresh ground pepper (check out Penzey's )
3 c. milk
3 c. chopped smoked Turkey
1 jar sliced mushrooms, drained
1 c. white wine
1 c. shredded parmesan cheese
1 c. sliced almonds
3 T. chopped fresh parsley ( I used about 1 1/2 T. of dried)

Melt butter in large skillet. Add onion and saute until tender. Gradually stir in flour and next 2 ingredients until smooth. Add milk and cook, stirring constantly, for 5 minutes or until thickened. Remove from heat and stir in Turkey, mushrooms and wine.

Layer in 9x13 dish, 1/2 the pasta, 1/2 Turkey mix, and 1/2 c. parmesan cheese. Repeat with pasta and turkey mix.

Combine remaining 1/2 c. parmesan cheese, almonds and parsley. Sprinkle over the casserole.

Bake at 400 degrees 20-25 minutes.
