Spiced Ground Beef Sandwiches

Sloppy Joes—those sandwiches of tomato-infused ground beef in hamburger buns—may well be as American as apple pie, but kheema paav, often made with ground mutton or lamb, is the equivalent in Mumbai and Delhi, a street food invented by vendors of the Muslim faith and devoured by all who eat meat. Both sandwiches are designed to be eaten on the run, at a picnic, or even at a simple family dinner, with the Indian version—no surprise—packing more oomph.
