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...

Macaroni & Cheese, kinda!-imageuploadedbytapatalk1408335170-601282-jpg
Ingredients
1 tablespoon coconut oil
1 tablespoon flour
1 cup almond milk
cup nutritional yeast
1 teaspoon Dijon mustard
teaspoon turmeric

Salt and pepper to taste (we use teaspoon salt and a few shakes of pepper)

Instructions
1
Melt the coconut oil in a small saucepan over medium heat, then add the flour and mix to form a paste.
2
Add the milk and stir well to remove any lumps. Keep stirring every few minutes until the sauce thickens and bubbles.
3
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.
