A very simple and tasty dish for all beginners. Cooked with very minimum spices, this dish comes in handy when we run out of onions and tomatoes. This dish can be prepared sweet and sour(completely optional if you like it)and is a hit item in states like west bengal and orissa. It was during my trip to kolkata in jan that i happened to try this at one of the restaurants and liked it so much that i tried making it at home. I hope you all like it.
