Presoak 12 wooden skewers in warm water. Mix together the peanut butter, soy sauce, lime juice, curry powder, garlic and hot pepper sauce in a large bowl.
Put the chicken in the marinade and leave to marinate in the refrigerator for about 8 hours or overnight.
Thread the chicken onto skewers and transfer to a foil-lined grill pan. Cook under a preheated hot grill for 5 minutes on each side.
