1. Combine the beef mince with grated onion, minced garlic, cumin, coriander, smoked paprika, salt and pepper. Mix well. Shape into oval koftas around skewers (or roll into sausage shapes if not using skewers).
2. Make the yoghurt sauce: mix Greek yoghurt with a grated garlic clove, a squeeze of lemon, fresh mint (finely chopped) and a pinch of salt.
3. Prep the salad: dice the tomatoes, thinly slice the red onion, toss with rocket and a squeeze of lemon and a drizzle of olive oil.
4. Warm the naan breads: wrap in foil and heat in a 180°C oven for 5–6 mins, or toast briefly in a dry pan.
5. Fry the koftas: heat a splash of oil in a large frying pan over medium-high heat. Cook koftas 8–10 mins, turning regularly, until browned all over and cooked through.
6. Serve koftas on top of warm naan, drizzle with yoghurt sauce and top with the side salad.
