Take the mint leaves, green chillies and ginger in a mixer. Squeeze lemon over and grind to fine puree. Include water for ease of grinding.
Heat a pressure cooker with all the tempering ingredients. Saute for a while and then include onion slices. Saute till they turn translucent.
Include potato cubes, peas and turmeric powder. Stir until everything mixes up. Next pour in the mint plus spices puree.
Continue sauteing till the puree coats well on veggies. Drain water from rice and add to the sauteed veggies. Give a quick mix.
Add 1.5 cup of water, garam masala powder, salt and close the lid. Pressure cook for 3 whistles in medium flame and switch off. Let the pressure subside, then open the lid, fluff and serve.
