Crock pot Mac and cheese

Today I made Mac and cheese in the crock pot for lunch. Try this : 2 cups of milk, 4 cups of mostly cooked macaroni noodles, 1 can of cream of mushroom soup, 1 tsp of mustard, 1/2 cup of sour cream and pepper. Cook on low for 3 hours. Stir in 2 cups of shredded cheese when it is time to eat. This is enough for 4 people. Great to pack in a lunch the next day.
