01 - Rinse the rice under cold water until the water runs clear. Combine rice, water, and salt in a saucepan and bring to a boil over medium-high heat. Cover, reduce heat to low, and simmer for 15 minutes. Remove from heat and let steam, covered, for 10 minutes before fluffing with a fork.
02 - In a mixing bowl, toss the chicken pieces with 2 tbsp soy sauce and 1 tbsp cornstarch until evenly coated. Let the chicken marinate for 10 minutes at room temperature.
03 - In a small bowl, whisk together 4 tbsp soy sauce, honey, rice vinegar, sriracha, grated ginger, minced garlic, and pineapple juice until smooth and well combined.
04 - Heat vegetable oil in a large skillet or wok over medium-high heat. Add the marinated chicken pieces in a single layer and cook for 5 to 6 minutes, turning occasionally, until golden brown and cooked through. Transfer the chicken to a plate and set aside.
05 - In the same skillet, add a splash of oil if needed. Stir-fry the red onion and bell pepper for 2 to 3 minutes until slightly softened. Add the sugar snap peas and pineapple chunks, cooking for another 2 minutes until heated through but still crisp-tender.
06 - Return the seared chicken to the skillet. Pour the prepared sauce over the chicken and vegetables, tossing everything to coat evenly. Cook for 2 minutes until the sauce thickens and clings to the chicken and vegetables.
07 - Divide the cooked rice among four bowls. Top each bowl generously with the chicken, pineapple, and vegetable mixture. Garnish with sliced spring onions and toasted sesame seeds. Serve immediately.
