Cajun Alfredo Sauce & Grilled Chicken

During the holidays, with so many dinners of "tradition" including Turkey, Ham, Dressing, Stuffing, Sweet Potato This & That, Baked Goods Galore...I find myself wanting something that is not the norm, a bit on the spicy side! This is one of my favorites!

Cajun Alfredo Sauce
1/2 cup (1 stick) unsalted butter
1 12 oz pkg frozen seasoning blend  or
(the cajun trinity - 1 cup chopped onions, 1 cup diced celery, 1 cup diced red or green bell pepper)
2 tsp chopped or minced garlic
1/8 tsp celery salt
16 oz heavy whipping cream (2 cups)
16 oz half/half  (2 cups)
8 oz shredded parmesan cheese
1 cup chopped provolone cheese
salt and pepper to taste (or Tony Chachere's Creole/Cajun seasoning , about 1-2 Tbsp. my preference)

2 Tbsp. fresh snipped parsley for garnish

Saute vegetables in melted butter for 10 minutes...add remaining ingredients, cook until
thickened...if too thick, add milk until reaches desired consistency.
Toss with  fettuccine noodles topped with grilled chicken breast. Garnish with parsley.

6-8 boneless, skinless chicken breasts
Weber's Kickin' Chicken seasoning

Season both sides of chicken breasts. Brush grill pan with oil. Heat over med high heat. Add chicken and grill 4-5 minutes per side or until cooked through. For marking chicken, rotate 1/4 turn halfway through cooking on each side.
