Clean Eating Green Bean Casserole

I love green bean casserole, but Campbell's cream of mushroom soup and canned fried onions aren't really the pinnacle of health.  This is a fantastic, fresh alternative that would be a welcome addition to any Thanksgiving feast (plus its gluten free and dairy free)!

Ingredients:

1 yellow onion, sliced thinly
1 tablespoon coconut oil, or butter
2 cups parsnips, chopped
10 oz. mushrooms, chopped
3 cloves garlic, minced
1/4 cup nutritional yeast
1 1/2 cups water
1 1/2 teaspoons fine sea salt
1 lb. fresh green beans
