01 - In a large 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 the bowl with plastic wrap and refrigerate for at least 1 hour, or up to 4 hours for deeper flavor penetration.
03 - Preheat an outdoor grill or indoor grill pan over medium-high heat. If using wooden skewers, soak them in water for at least 30 minutes beforehand to prevent burning.
04 - Remove the chicken from the marinade, allowing excess to drip off. Thread the chicken pieces evenly onto the prepared skewers, leaving a small gap between pieces for even cooking.
05 - Place the skewers on the hot grill and cook for 5 to 7 minutes per side, turning once, until the chicken is cooked through and lightly charred with grill marks. Internal temperature should reach 165°F.
06 - While the skewers grill, combine the honey, soy sauce, water, minced garlic, and chili flakes in a small saucepan. Bring to a gentle simmer over medium heat.
07 - Stir in the cornstarch slurry and continue whisking constantly for about 1 minute until the sauce thickens to a glossy glaze consistency. Remove from heat immediately.
08 - Arrange the grilled chicken skewers on a serving platter, drizzle generously with the honey garlic sauce, and garnish with sesame seeds, sliced green onions, and lime wedges.
