It can be hard to find a casserole dish that's vegetarian. Most casseroles are meant to be complete meals for families that eat meat. In addition, they typically include only a starch and some vegetables as well as meat. As the recipe below shows, however, it's entirely possible to make a vegetarian casserole whether it's because you're a vegetarian or because you just need a vegetable dish as a side.
You can't get much healthier than this version. Zucchini and sweet potatoes are both packed with tons of nutrients and vitamins, and you'll feel better after eating it because you've done something amazing for yourself. In fact, it's so delicious, even those who eat meat will love it.
