Step 1: Prepare the Chicken : In a medium bowl, combine chicken pieces with soy sauce, mirin, sesame oil, and pepper. Mix well and marinate for 10–15 minutes while preparing the sauce and vegetables.
Step 2: Make the Teriyaki Sauce : In a small saucepan, whisk together soy sauce, honey, rice vinegar, mirin, garlic, and ginger. Bring to a gentle simmer over medium heat. Stir in the cornstarch slurry (2 tsp cornstarch + 2 tbsp water) and cook until the sauce thickens and becomes glossy. Stir in sesame oil, then remove from heat and set aside.
Step 3: Cook the Chicken : Heat a non-stick skillet over medium-high heat. Add the marinated chicken and cook for 4–5 minutes per side, until browned and cooked through. Pour half of the teriyaki sauce over the cooked chicken and toss to coat. Let it simmer for 1–2 minutes until the sauce thickens and glazes the chicken beautifully.
Step 4: Steam the Vegetables : While the chicken cooks, bring a small pot of water to a boil and place a steamer basket on top. Add broccoli, carrots, snow peas, and bell pepper. Cover and steam for 3–5 minutes until tender but still crisp. Remove from heat and season lightly with salt if desired.
Step 5: Assemble the Rice Bowls : Add a scoop of cooked jasmine rice to each bowl. Arrange teriyaki chicken on top, followed by steamed vegetables. Drizzle remaining teriyaki sauce over the bowl. Garnish with sesame seeds and chopped green onions.
