Creamy Crock Pot Mac N Cheese

I orginially found this recipe in a cooking magazine but changed some ingredients to get the consistency my family loves. Hope yours will too.

Cook shell macaroni according to package directions.

Drain.

Place cooked shells in a 5-quart greased crock pot.

Add margarine and stir to cover.

In a sauce pan over medium heat , combine soup and 1 / 2 and 1 / 2.

Stir until smooth.

Add eggs and dry mustard and stir until combined.

Add cheese and stir until completely melted and smooth.

Pour cheese sauce over shells and stir well.

Cover and cook on low for 2 1 / 2 - 4 hours.
