Best Vegan Cheese Sauce

Very tasty recipe, I think it is the onion cooked with it. I use a tin of white beans more economical. My go to recipe.

Bean only version tasted good but didn't have the creaminess and didn't stick to chips or anything else well. It also did not freeze well. The half bean half cashew version was really good and had more creaminess and held on to other foods better. It looked weird after freezing it, but was back to being smooth after warming it up. The cashew only version has the the best texture and taste though.
