Pat the chicken thighs dry with paper towels and trim any excess fat. If the pieces are large, cut them into 2–3 inch chunks so they cook quickly and evenly and absorb more flavor.

In a medium bowl, whisk together the soy sauce, honey, rice vinegar, toasted sesame oil, water, minced garlic, grated ginger, sriracha (if using), sesame seeds, and black pepper. Taste and adjust sweetness or salt as desired.
1/3 cup low-sodium soy sauce, 3 tablespoons honey, 2 tablespoons rice vinegar, 2 tablespoons toasted sesame oil, 2 tablespoons water, 3 cloves garlic, 1 tablespoon fresh ginger, 1 tablespoon sriracha or other chili sauce, 1 teaspoon sesame seeds, 1/2 teaspoon black pepper
Place the chicken in a large zip-top bag or shallow dish. Pour in about two-thirds of the marinade and toss to coat. Reserve the remaining marinade in a small bowl for later. Let the chicken marinate for at least 20 minutes at room temperature, or up to 8 hours in the refrigerator.

Whisk the cornstarch into the reserved marinade until completely smooth with no lumps. Set aside near the stove; this will become the thickened sauce for the chicken.
1 tablespoon cornstarch
Heat 1 tablespoon of the neutral oil in a large skillet or wok over medium-high heat. Add the bell pepper, snap peas or green beans, broccoli, or any combination of veggies you like. Stir-fry for 3–4 minutes until crisp-tender. Transfer to a plate and set aside.

In the same skillet, add the remaining 1 tablespoon neutral oil. Remove the chicken from the marinade, letting the excess drip off, and discard the used marinade. Add the chicken in a single layer, working in batches if needed. Cook for 4–5 minutes on the first side without moving it much to develop a good sear.

Flip the chicken pieces and cook for another 3–5 minutes, until cooked through and the internal temperature reaches 165°F (74°C). If using chicken breasts, reduce the cook time slightly and watch closely to avoid drying them out.

Stir the cornstarch-marinate mixture, then pour it into the skillet with the cooked chicken. Reduce the heat to medium. Stir gently and let the sauce bubble for 2–3 minutes, until it thickens into a shiny glaze that coats the chicken.
1 tablespoon cornstarch
If you cooked veggies, add them back into the pan and toss with the chicken and sauce until everything is evenly coated and heated through.
1 red bell pepper, 1 cup snap peas or green beans, 1 cup broccoli florets
Turn off the heat. Sprinkle sliced green onions and extra sesame seeds over the top. Taste and adjust seasoning if needed. Serve immediately over cooked rice, brown rice, or noodles.
