Chorchori or charchari is a staple of Bengali vegetarian cuisine. It usually consists of around 5 different vegetables sauteed and steamed. The exact selection of veggies depends on what you happen to have available, and you should try to have a range of different textures - crunchy like carrots and radishes, soft like squash, pumpkin and aubergine, and in-between like potatoes, peas and green beans.
