Sambharo is nothing more then vegetables sautéed in oil with mustard seeds, green chilies, turmeric powder. You can serve it as a side dish or make it a warm salad or filler for sandwich as well. You can use all kinds of vegetables combination, carrots and green capsicum, green papaya and chilies, red cabbage and beets but my favorite is famous guajarati dish, which has cabbage, carrot and green mango. You can substitute green mangoes with vinegar or lime juice.
