Casserole of vegetables with mushrooms

In autumn and winter, we crave colorful, tasty food even more. Plus, it's also healthy because of the many super vegetables it contains. The vegetable casserole with mushrooms is a meat-free one-dish dish that is substantial even when eaten alone, but can also be served as a side dish. The vegetables can be varied as desired, and I would definitely not leave out mushrooms, sweet potatoes, eggplant and onions. Make it yourself!
