Vegan Dairy Free Cheese and Onion Sauce

I use this for a few things, It's great for lasagna, as a gravy substitute or with roast vegetables.
Basically a bechamel sauce with the added goodness of onions for flavor and a sprinkle of nutritional yeast for cheesiness.

Ingredients
4 Tbsp Vegan Butter
3 Tbsp Plain Flour
2 Cups of Dairy free milk
1 Onion Finely diced
3 Tbsp of Nutritional yeast or to taste Can be bought from health food stores
Salt & White pepper to taste

Instructions 
In a small sauce pan add milk and onions over medium heat till the onions become translucent, add salt and pepper and nutritional yeast and stir well.
In a larger pot add butter and flour to make a roux and stir well for approx 6mins to cook out the flour taste, Take the pot with the roux off the hotplate and using a whisk slowly add the milk to the flour and butter whisking well,5 when its well combined pop it back on medium heat to thicken still constantly whisking. Makes heaps for a large lasagna with extra left over, Alternatively halve the ingredients to make less. "Enjoy"  =)
