There's nothing quite so comforting as a bowl of lentil soup, and this version is full of flavor and super easy to fix in the slow cooker. As if you need another reason, the soup is also a budget-friendly choice, and you probably have most of the ingredients and seasonings on hand. Instead of plain water, use half unsalted vegetable broth or chicken stock for extra flavor. Or use other kinds of vegetables if you like. Feel free to omit the bacon for a vegetarian soup. A cooking time of 7 to 9 hours is a real convenience if you have to work or have a busy day ahead. If you would rather cook the soup faster, set it on high and cook it for about 3 to 4 hours. Serve this easy, great tasting lentil soup with cornbread, crackers, or freshly baked biscuits.
