In a bowl, combine the peri-peri sauce, minced garlic, olive oil, lemon juice, salt, and pepper. Mix well to create the marinade.
Place the chicken pieces in a large dish or resealable plastic bag and pour the marinade over them, ensuring the chicken is well coated. Marinate in the refrigerator for at least 2 hours or overnight for best flavor.
Preheat the grill to medium-high heat.
Remove the chicken from the marinade and grill for about 20-25 minutes, turning occasionally, until the chicken is cooked through and has nice grill marks.
Serve the peri-peri chicken hot, garnished with chopped fresh parsley if desired.
Enjoy!
