You first wrap the marinated veggies in silver foil and cover it with dough. Then place it on a tawa and cook it in sand 

For those who don't shy away from slow-cooking methods, sand roasting might be an option they'd like to try, feels Rahul Kulkarni, executive chef, Irish House. He first came across the technique during his days in Goa, where sand roasting is a popular group cooking activity, especially on camp nights. "It's popular in coastal areas, where sea sand is available aplenty. I've given it my own spin, so that you can pull it off too," says the chef.
