Add quinoa to a small saucepan with the chicken broth then bring to a boil, place a lid on top, turn heat to low and cook until quinoa has absorbed chicken broth, about 15 minutes. Fluff with a fork then set aside.
Combine all sauce ingredients in a microwave-safe bowl then microwave for 20 seconds. Stir until smooth then set aside. Whisk together egg and sesame oil in a small bowl then set aside.
Heat 1 teaspoon peanut oil in a wok or large skillet over high heat. Season chicken with salt and pepper then add to wok and stir fry until no longer pink. Remove to a plate then set aside.
Heat remaining teaspoon peanut oil in wok then add coleslaw mix, frozen edamame, and green onions. Stir fry until tender, 2-3 minutes, then push to outsides of wok, creating a clear space in the center. Add egg whisked with sesame oil to center of wok then stir fry until soft scrambled.
Add cooked chicken, quinoa, sauce, and half the chopped peanuts to wok then toss to combine. Serve with remaining chopped peanuts.
Notes
Throw in any leftover veggies when you stir fry! You can also make extra quinoa earlier in the week to be ready to make this.
