Add freshness to a barbecue or Indian meal with a relish that is packed with tomatoes, onion and coriander – and it can be made a few days ahead
Mix together all the ingredients, except the coriander, with a pinch of salt. (Can be done up to three days ahead and kept in the fridge.) Stir through the coriander just before serving.
