Soften the bread in water, press out the liquid and tear into small pieces. Add the mince, egg, breadcrumbs and mango chutney and season with salt, pepper, lemon juice and garam masala. Mix well by hand and, with lightly floured hands, form into evenly-sized balls (3.5 cm diameter). Heat the oil in a non-stick frying pan and fry the balls all over, over a medium heat for approx. 8 mins. Combine the yoghurt and peppermint and season with salt and pepper. Using toothpicks, stick the mango segments onto the balls while still hot and serve with the yoghurt dressing.
