Mirchi Ka Salan is a popular Indian side dish that pairs perfectly with biryani. It is made with long green chillies cooked in a tangy and spicy peanut and sesame seed gravy. The dish has a rich and creamy texture with a hint of sweetness. The spiciness of the chillies is balanced by the nutty flavors of the gravy, making it a delicious accompaniment to biryani.
