This hearty vegetarian chili is packed with flavor and nutrition. The sweet potatoes and black beans provide a good source of fiber and protein, while the spices add a depth of flavor. The chili can be made on the stovetop or in a slow cooker, and can be served with toppings like avocado, cilantro, and sour cream. It's a perfect meal for a cold winter day, and can be made in large batches for meal prep or leftovers.
