In skillet, heat oil on med high. Stir-fry chicken and garlic 3 or so minutes. Remove the chicken. Spoon peanut butter into skillet. Whisk in water, vinegar, soy sauce, pepper flakes and 1 seasoning packet from noodles. Do not use both packets (strong flavor).
Bring to a boil: add noodles breaking them up slightly. Add cooked chicken and cover. Simmer 4 minute to separate noodles. sprinkle with veggies cover and simmer 3 more minute Stir. Add green onions on top. I also added some chopped peanuts on top. Serve and enjoy! Just as good the next day.
