Layers of spaghetti squash, caramelized mushrooms and onions, and fresh spinach meld together in this delicious casserole. Simple yet elegant to serve as either a main or a side dish at a vegetarian dinner party, if desiring to make it completely vegan, substitute out the cheese for a rice or soy-based vegan version.
