Swiss Cheese-Mushroom Pasta

6 Chicken Breasts- I usually only use 4 because I like mine more saucy
1 jar 4 Cheese Alfredo Sauce
1 can cream of chicken
2 c. real bacon bits, or how ever much you like
1 pkg. fresh sliced mushrooms
1 pkg Italian dressing mix
1 pkg cream cheese - I have done it with or without this. The original recipe doesn't call for it. I think I forgot and just added it once on accident!
8 oz. Swiss cheese, grated
1/4 stick butter melted
garlic salt & pepper to taste
1/4 cup milk (use milk to get rest of Alfredo sauce out of jar, add however much to thin out sauce)
frozen peas-however much your family likes

Combine everything in crock pot and cook on low 7 hours. If you cook on high without stiring the cheese burns on bottom. Add peas last hour so they don't get over cooked. Shred chicken and serve over pasta.

**I freeze half of the sauce for later because it makes so much.**
