Green Tomato Kootu is a traditional South Indian dish made with unripe green tomatoes and lentils. It is a flavorful and nutritious curry that is easy to prepare. The tangy and slightly sour taste of the green tomatoes pairs well with the earthy lentils and aromatic spices. This kootu can be enjoyed as a side dish with rice or roti, and it is a great way to use up green tomatoes from your garden or local market.
