In a small to medium bowl, whisk together the soy sauce and cornstarch until smooth.
Add the chicken broth, oyster sauce, sesame oil, rice vinegary, brown sugar, and Sriracha and whisk to combine. Set aside.
In a large skillet or wok, add the olive oil over medium-high heat.
Add the ground chicken and cook until cooked through and golden, breaking into smaller pieces as it cooks.
Once cooked, add the garlic and ginger, and cook another minute.
Add the cabbage, carrots, bell pepper, and onion and toss well to combine. You can add another 1-2 tablespoon of olive oil, too, which I do. Cover with a lid and let it cook for 10-13 minutes, stirring occasionally so the bottom doesn't burn.
While the veggies are cooking, also cook the noodles according to package directions.
Once the vegetables and noodles are cooked, add the noodles and sauce to the vegetables and toss well to combine. Cook another 2-3 minutes to let the sauce thicken up.
Serve topped with diced green onions. Enjoy!
