Make the shawarma marinade

• In a mixing bowl, combine the olive oil, lemon juice, crushed garlic, cumin, coriander, paprika, turmeric, cinnamon, salt and black pepper.
• Whisk until the spices are evenly blended.

Marinate the chicken

• Add the chicken cubes to the marinade and toss until every piece is well coated.
• Cover and refrigerate to let the flavours develop.

Thread the skewers

• Thread the marinated chicken pieces onto the skewers, leaving a little space between them.

Grill the skewers

• Grill the skewers over medium-high heat, turning regularly, until the chicken is cooked through and nicely charred at the edges.

Rest and serve

• Let the skewers rest briefly, then serve hot with flatbread, salad or a yogurt sauce.
