Green Bean Casserole With Mushroom Sauce And Crispy Onion

"Confession: this Healthy Green Bean Casserole is the first one I've ever tried! Are you judging my lack of thanksgiving food prowess? It's ok, I'm judging myself. But it was totally worth the 26 years it took me to put this in my face because this bad boy is SO rich and creamy... when you find out it's totally Paleo and vegan friendly and whole30 compliant, you're gonna be like WHOAA Srsly. Warm comfy thanksgiving food vibes and general goodness. It's what we're talking about right now. "
