01 - In a mixing bowl, whisk together the soy sauce, sesame oil, rice vinegar, honey, minced garlic, grated ginger, and black pepper until well combined.
02 - Add the chicken pieces to the marinade and toss to coat evenly. Cover and refrigerate for at least 1 hour, or up to 4 hours for deeper flavor.
03 - Preheat an outdoor grill or grill pan over medium-high heat.
04 - Thread the marinated chicken pieces onto soaked wooden skewers or metal skewers, dividing the meat evenly.
05 - Grill the skewers for 5 to 7 minutes per side, turning once, until the chicken is cooked through and lightly charred.
06 - While the skewers cook, combine the honey, soy sauce, water, minced garlic, and chili flakes in a small saucepan. Bring to a simmer over medium heat.
07 - Stir in the cornstarch slurry and whisk continuously until the sauce thickens, about 1 minute. Remove from heat.
08 - Arrange the grilled chicken skewers on a platter, drizzle with honey garlic sauce, and garnish with sesame seeds, sliced green onions, and lime wedges.
