Levantine
Cut the chicken into 3-4 cm cubes.
In a large bowl, whisk the yogurt, lemon juice, olive oil, garlic, tomato paste, paprika, salt, pepper and allspice.
Add the chicken, toss to coat, cover and marinate in the refrigerator for at least 4 hours or overnight.
Thread the chicken onto 8 skewers, leaving small gaps between the pieces, and let the excess marinade drip off.
Grill over hot charcoal or on a preheated grill pan over high heat for 10-12 minutes, turning every 3 minutes, until charred at the edges and 74C inside.
Rest the skewers for 3 minutes.
Serve with garlic sauce (toum), pickles and warm pita bread.
