Unquestionably, yes! Lentils are a plant-based food source and contain no animal products or by-products, making them a nutritional cornerstone for many vegan and vegetarian diets. In addition, they're packed with protein (roughly 24 grams per half cup, which is 20% of the recommended daily value) and fiber (10 grams per half cup, which is 37% of the recommended daily value), which can help in satisfying hunger and aiding in digestion.
