Lemon Green Moong Dal Rasam is a tangy and flavorful South Indian soup made with split green gram lentils, lemon juice, and a blend of spices. This comforting and nutritious dish is packed with protein and vitamins. The lentils are cooked until soft and then tempered with mustard seeds, cumin seeds, curry leaves, and dried red chilies. The addition of lemon juice adds a refreshing citrusy flavor to the rasam. Serve this rasam hot with steamed rice or enjoy it as a light soup on its own.
