Take a vessel and mix together, the pumpkin pieces, chopped stems and leaves, green chillies, coconut, salt as per taste, 1/4 tsp of sugar and 1/4 cup or less of water. Cover the vessel and leave it on a low flame for 10 mins. Stir well and leave covered for another 10 mins. Once the pumpkin is cooked, it's ready.
This goes best with rice as an accompaniment.
