Tip:You can make the harissa up to a month in advance and keep in an airtight container in the fridge, simply drizzle enough olive oil to cover the surface to keep it fresh.
If using whole chicken wings, separate them by cutting through the joint with a sharp knife, leaving you with a drumette and a flat.
Place the chicken wings in a large bowl then season with salt and pepper and toss to make sure the chicken is evenly seasoned.
Pour over the harissa paste and stir to coat the chicken.
Cover with plastic wrap and allow to marinade for at least 30 minutes but ideally overnight in the refrigerator.
Preheat an outdoor grill to medium-high heat then add the chicken wings.
Grill until golden brown and cooked through then remove and serve with fresh coriander/cilantro and lemon wedges.
