1In large bowl, stir together 1/2 cup coconut milk, 1 clove garlic, 1 tablespoon brown sugar, 1 teaspoon gingerroot, the curry powder, salt and pepper. Add chicken; stir to coat. Cover; refrigerate at least 1 hour to marinate, stirring occasionally. Meanwhile, soak skewers in water at least 30 minutes before using to prevent burning.
2In 2-quart saucepan, heat vegetable oil over medium heat. Cook onion in oil about 5 minutes, stirring frequently, until soft. Add 2 cloves garlic and 2 teaspoons gingerroot. Cook 1 minute longer, stirring constantly. Add remaining sauce ingredients except cilantro. Stir until sauce is smooth and thoroughly heated, about 3 minutes. Remove from heat; stir in cilantro. Pour into small bowl for dipping; set aside.
3Heat gas or charcoal grill. Remove chicken from marinade; discard any remaining marinade in bowl. Thread chicken strips on skewers. Place skewers on grill over medium heat. Cover grill; cook 8 to 10 minutes, turning once, until chicken is no longer pink in center.
4Serve chicken with lime wedges and dipping sauce.
