01 - Whisk together soy sauce, honey, pineapple juice, rice vinegar, garlic, ginger, sesame oil, and black pepper in a bowl. Place chicken in a resealable bag or shallow dish, pour marinade over, and coat evenly. Marinate for at least 15 minutes, up to 2 hours refrigerated for deeper flavor penetration.
02 - Combine rinsed jasmine rice, coconut milk, water, and salt in a medium saucepan. Bring to a boil, reduce heat to low, stir once, cover tightly, and simmer for 15 minutes. Remove from heat and let stand covered for 10 minutes to steam. Fluff gently with a fork before serving.
03 - Preheat grill or skillet over medium-high heat. Remove chicken from marinade, allowing excess to drip off. Grill or sear for 5–7 minutes per side until cooked through (internal temperature reaches 165°F) and exterior is slightly caramelized. Discard any remaining marinade.
04 - Transfer cooked chicken to a cutting board and let rest for 5 minutes to allow juices to redistribute. Slice into strips or leave whole, depending on preference.
05 - Mound coconut rice onto plates and top with chicken. Garnish generously with pineapple cubes, green onions, toasted coconut flakes, sesame seeds, and fresh cilantro leaves. Serve immediately while warm.
