For the koftas: Place the spinach in a pan, and pour 2 cups of water over it. Cook until the spinach becomes tender. Drain well and reserve the cooking water, we will use it later on for the sauce.

In a large bowl, mix all the kofta ingredients until you form a dough. Then divide the dough into small balls.

Fry the kofta balls in very hot oil until tender, yet still green in color.

For the sauce:

Heat the oil in a large saucepan and then stir in the onions, green chilis and ginger until they become tender. Add in the tomatoes, turmeric, cayenne, coriander, cumin and salt. Simmer over low heat.

When the sauce starts to thicken, add in the fried kofta balls and keep simmering for few minutes over low heat. Remove from heat.

Serve hot with rice.
