A perfect dinner for those nights when you could just use something hearty and warm, this classic French lentil stew is a vegetarian delight. Simple to prepare and comforting to the senses, once you make this, you’ll want to keep lentils on hand more often. If you can’t wait around for the lentils to cook, start the dish in the morning and let the softened savories, lentils, herbs, and broth cook in the slow cooker for 4 hours on high or 6 on low and add the greens twenty minutes before serving.
