Put the pork in a large bowl with the oil, oregano, lemon zest and juice and paprika as well as a good pinch of salt. Toss everything together to combine and leave to marinate for 10 mins.

Combine the yogurt, garlic and cucumber together in a bowl. Season with salt and set aside.

Heat the grill to high. Thread the marinated pork and the peppers on four metal skewers, alternating between the pork and peppers as you go. Place on a non-stick baking sheet and grill for 3-4 mins on each side, or until cooked through and golden brown.

Serve with the lettuce, yogurt mixture and chilli sauce, and flatbreads, if you like.
