Vegan Cauliflower Alfredo Sauce

"Creamy Cauliflower Alfredo pairs perfectly with your favorite pasta. This lightened up version of the classic sauce is smooth and silky without containing a drop of butter or dairy. While tomato-based pasta sauces are my usual go-to recipes, sometimes I'm in the mood for something more comforting and decadent. I often turn to my favorite dairy-free creamy pasta sauces made with cashews. But they tend to be on the heavy side, and those with tree-nut allergies have to avoid them. And that's where this Cauliflower Alfredo recipe comes in. When you taste it, it's hard to believe it's low-fat, dairy-free, and nut-free."
