- In a large measuring cup, whisk corn starch and water together until combined. Stir in remaining sauce ingredients and whisk until smooth. Set aside. 
- Heat your large pot to medium and add oil. Add chicken breasts to the pan and spread them out throughout the pan. Season with salt and pepper. Cook for 3-4 minutes untouched, then stir. Continue cooking for a few minutes until all sides are golden brown, stirring again as needed. It's okay if your chicken isn't fully cooked through yet. 
- Add vegetables and stir. Cover, and cook for 2-3 minutes. Stir again. 
- Push chicken and vegetables to one half of your pan to make room for the noodles. Add noodles to the empty space, and then pour the sauce directly over top. Cover and cook, untouched, for 3-4 minutes. 
- Stir, and gently start to break up the noodles. Cover again, continuing to cook for a few minutes at a time until noodles and veggies are cooked through. 
- Serve with sliced green onion, sesame seeds, and/or spicy mayo. Enjoy! 
- If you'd prefer to use store bought sauce, you'll need about 2 cups. Thin with water or add extra sauce as needed.
- To use rice noodles or soba noodles, cook them separately and stir them in at the end.
