Comforting Mushroom Casserole

Ingredients

 1 ½ cups white beans (home-cooked or BPA-free canned, drained and rinsed)

 1 batch Cauliflower Squash Cheese Sauce (link in Chef’s Notes)
 1 cup carrots (sliced)
 1 ½ cups yellow onions (sliced)
 3 cups mushrooms (sliced)

11

Pour the remaining cheese sauce on top.
