Cook your sweet potatoes in a slow cooker so you don't have to heat up your house. They'll technically take longer than in an oven, but you don't have to sit around and wait for them, so it seems like they're done in minutes! Just throw them in the slow cooker right before hopping into bed and you'll be waking up to warm, sweet, and soft sweet potatoes. Use them for dinners or for this almond butter banana sweet potato breakfast.
