Granny Apple Sweet Potatoes

Sweet potatoes and Granny Smith apples complement each other in this terrific side dish that’s ideal for holiday meals. Not only is it a great change from the overly sweet marshmallow-topped sweet potato casserole, but it’s also more practical because it’s made in a slow cooker, so it frees up oven and stove space for the rest of your dinner. Use more or less sugar, according to your personal preference. For a soy-free version, use a soy-free vegan butter.
