These Indian-inspired burgers are made with lean ground turkey and flavoured with tikka paste and yogurt. If you have the time, make these burgers a few hours in advance, which will allow the flavours to marinate the meat. Serve the burgers in halved baby naan breads with some baby spinach leaves and a spoonful of tzatziki. These burgers can be frozen. Open-freeze the patties on a tray lined with greaseproof paper until firm, then pack into labelled containers or freezer bags and freeze for up to 1 month. Defrost thoroughly in the fridge before cooking.
