Wash and peel the ridge gourd and radish and make small pieces.

Heat oil in a pan or pressure cooker and add cumin and green chilies.

When cumin becomes golden in colour, add turmeric and chopped vegetables.

Add salt and mix well.

Pressure cook or cook in the covered pan till done. No need to add water as the vegetables release enough water while cooking.

When done, mash it slightly and add lemon juice and fresh coriander.

Serve hot with roti or rice.
