Creamy Chicken and Ham Medley

Creamy Chicken & Ham Medley by Crock Pot
4 oz sliced mushrooms, drained
1/3 c butter
1/3 c flour
2 1/2 c milk
1 c grated parmesan (I use fresh)
1/2 t salt
1/4 t black pepper
1/4 t nutmeg
dash ground pepper
2 c cooked chopped chicken (I pre-cook chicken and keep in freezer)
2 c cooked chopped ham
2 pk (10 oz ea) frozen puff pastry shells, baked (I don't use shells, I use sheets)

1. Melt butter in Crock; stir in flour. Stir in remaining ingredients except pastry. Cook on low until thickened, stirring every hour. It's ready to serve after 2 1/2 hours.
2. Bake shells as directed. Spoon medley into shells. Sprinkle with paprika, serve.

This is just wonderful! We don't always have ham in it and it's just as good. Don't forget, you can always use leftover Thanksgiving/Christmas turkey.
