I found this recipe a while back, and then got the "nootch" so I could try it... Very tasty!
Dear Hubby didn't realize it wasn't cheese!

I used whole, cow milk - and skipped the turmeric. Used Orzo pasta...

Nutritional Yeast "Cheese" Sauce
Cook Time:10 Min Total Time:10 Min
Serves 2
Macaroni & Cheese, kinda!-imageuploadedbytapatalk1408335170-601282-jpg
1 tablespoon coconut oil
1 tablespoon flour
1 cup almond milk
cup nutritional yeast
1 teaspoon Dijon mustard
teaspoon turmeric
teaspoon paprika
Salt and pepper to taste (we use teaspoon salt and a few shakes of pepper)

Melt the coconut oil in a small saucepan over medium heat, then add the flour and mix to form a paste.
Add the milk and stir well to remove any lumps. Keep stirring every few minutes until the sauce thickens and bubbles.
Add the nutritional yeast, Dijon mustard and spices, and beat with a whisk until smooth, adding more milk if the sauce is too thick. Serve over veggies or pasta, use as a dip, or enjoy it any other way you can think of.
