Cook your base: Make a batch of rice according to package directions. Steam or sauté your vegetables until just tender.
Set aside to cool while you cook the chicken.
Season the chicken: Pat the chicken dry with paper towels. Toss with salt, pepper, and 1 tablespoon cornstarch to lightly coat.
Sear in batches: Heat a large skillet over medium-high. Add oil, then half the chicken.
Sear 3–4 minutes per side until golden and mostly cooked through. Remove to a plate and repeat with the remaining chicken.
Sauté the garlic: Lower heat to medium. If the pan is dry, add a splash of oil.
Add minced garlic and cook 30–45 seconds until fragrant, stirring so it doesn’t burn.
Make the sauce: In a small bowl, whisk honey, soy sauce, vinegar, sesame oil, red pepper flakes, water, and the remaining 1 tablespoon cornstarch until smooth.
Glaze the chicken: Return all chicken and any juices to the pan. Pour in the sauce and stir. Simmer 2–3 minutes, stirring, until the sauce thickens and coats the chicken in a glossy glaze.
Finish: Taste and adjust.
Add a touch more honey for sweetness or vinegar for brightness. Turn off heat. Sprinkle with green onions and sesame seeds.
Assemble meal prep: Divide rice among 4–5 containers.
Add vegetables. Spoon honey garlic chicken over the top. Let everything cool uncovered for 10–15 minutes before sealing.
