Lentil & Root Veggie Soup


French green lentils and black lentils hold up well to long, slow cooking without becoming mushy. Save the rinds from used-up blocks of Parmesan in a resealable plastic bag or tightly sealed container in the refrigerator. They give soup broths a rich, savory flavor.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
