Put the minced lamb, breadcrumbs, onion, parsley, rosemary, cumin, mint, chilli flakes or paprika, egg and Knorr Lamb Stock Cube into a food processor. Season with salt and pepper, then blend for about 30 seconds. Tip onto a plate, then cover and refrigerate for 1 hour.
Shape the mixture with your hands to create koftas, about the size of ping-pong balls.
Heat the olive oil in a large frying pan over a medium-high heat. Add the koftas and sizzle for 1 minute, then gently turn them over with a fork or spatula. Cook until crisp and brown. When cooked, drain on kitchen paper.
Whilst the koftas are cooling down, cook the halloumi in a char-grill pan or dry frying pan until golden on both sides. Warm the tortilla wraps or flat breads over the cooking halloumi.
Top the warm wraps or flat bread with rocket, tomatoes and red onion. Share the koftas between them and top with the halloumi. Serve, drizzled with a little olive oil and lemon juice and a pinch of sumac (if using).
