2 c. macaroni, cooked and drained
2 tbsp. oil
1 (12 oz.) can evaporated milk
1 1/2 c. milk
3 c. shredded sharp processed cheese
1/4 c. melted butter

I use 1 1/2 c. Cheez Whiz and 1 1/2 cups Velveeta.

Toss cooked macaroni in 2 tablespoon oil. Add all remaining ingredients. Pour into lightly greased crock pot. Stir well. Cover and cook on low 3-4 hours. Stir occasionally.
