Legumes

With about 19,000 different plant species claiming membership, legumes are the third most populous land-based plant family, coming in just behind #2—asters and #1—orchids. Legumes contain protein-building nitrogenic amino acids in their root nodes, so they are a terrific source of plant-based protein and make it easy to have regular Meatless Mondays. Usually low in fat and high in fiber, legumes are also a great option when planning Mediterranean diet-friendly meals, though you should check individual varieties of legumes for their specific nutritional information.
