New Cheese Sauce - almost healthy! (gluten-free)

Die deutsche Übersetzung findet ihr unter dem englischen Rezept!

I already have a really neat nacho cheese sauce recipe that is based on a very basic roux, but I am always happy to try something new. And this sauce is different, but equally awesome - and it's based on puréed veggies! And it's gluten-free for those of you who need to watch out for your wheat/gluten intake. Aaand it's soy-free, too. Both options are only true if you don't decide to use things like oat milk (gluten) or soy milk (ha! contains soy! ^^).
