Among the various types of dals (lentils), Toor Dal (Pigeon Pea) and Urad Dal (Black Gram) are among the highest in protein. Toor Dal contains approximately 22 grams of protein per 100 grams, while Urad Dal offers about 24 grams. Including these dals in your diet, perhaps in traditional Indian dishes like dal tadka or dal makhani, is a great way to increase protein intake.
