Chicken Saté Lettuce Wraps

Spray 10-inch ridged grill pan or skillet with nonstick cooking spray. Heat over medium-high heat until hot. Rub chicken with curry and salt. Add chicken to pan; cook 10 to 12 minutes or until it loses its pink color throughout, turning over once. From 1 lime, grate 1/2 teaspoon peel and squeeze 1 tablespoon juice. Cut remaining lime into wedges. In small serving bowl, whisk peanut butter, soy sauce, sugar, lime peel and juice, and 2 tablespoons very hot water until sauce is smooth. Slice chicken. Wrap some chicken, cilantro or mint, and cucumber with sauce in each lettuce leaf. Serve with lime wedges.
