Spicy bengal gram and potato gravy

Grams are rich in protien and bengal gram or kabuli chana is a good source of fiber. Giving that as a justification, I always try to use some sort of gram or lentil in everyday menu or atleast every alternate day. My mom makes this version for rotis and rice. It is healthy and tasty too. Spice variations are an individuals style, so this is just a base.
