I have blogged many "peeth perun" or vegetables cooked with besan/chickpea flour. A simple addition of besan makes a huge difference. Though the recipes for peeth perun bhajya are more or less same or similar, the vegetable used decides the overall flavor of the dish. So the side dish made with onions and besan will not taste the same as the one made with green tomatoes and besan.
