Prepare noodles according to the packaging instructions, drain, and set to the side.
Began by cutting up chicken thighs into bite-size pieces and place them into a small mixing bowl.
Top with salt and pepper and stir to coat the chicken.
Heat 3 tbsp. of oil over medium high heat in a wok or large sauté pan.
Add chicken pieces and allow to thoroughly brown, stirring occasionally. Be mindful not to stir too often as you want to leave time for the chicken to develop a crispy brown outside. Overall, it should take about 6 to 7 minutes.
Once cooked, remove chicken to a plate to the side. To the pan, add remaining 1 tablespoon of oil before adding in sliced onions, minced garlic, julienned bell pepper, and broccoli florets.
Cook for about five minutes, stirring occasionally.
While the veggies are cooking. Prepare the teriyaki sauce. In a small bowl, combine soy sauce, honey, brown sugar, sesame oil, and rice wine vinegar. Whisk well.
Once the veggies are done cooking, add back in chicken, along with prepared sauce.
In a small bowl, combine cold water and cornstarch and whisk to combine. Add to pan.
Simmer on low for 2-3 minutes to allow sauce to thicken.
Add cooked noodles to pan and stir to combine with sauce and other ingredients.
Enjoy!
