Add rinsed 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. (Can be done ahead of time.)
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.
Beyond the Label
Raw ingredient lists hide the volatile aromatic compounds released when chili garlic sauce and peanut butter meet hot fat. Heating the sauce components briefly activates capsaicin solubility, dispersing heat evenly across the lipids rather than creating isolated hot spots. Rinsing the quinoa prior to boiling removes bitter saponin coatings that would otherwise clash with the sweet tamari and rice vinegar profile. Thinly slicing the chicken breast maximises surface area for rapid protein coagulation in a scorching wok, locking in intracellular moisture before the exterior dries out.
The Chemistry of Emulsification
Microwaving the peanut butter, sugar, and tamari mixture for 20 seconds reduces fluid viscosity, allowing proteins in the peanut butter to form a stable emulsion with the liquid aminos and vinegar. Whisking the egg with sesame oil creates a lipid barrier around the albumen, preventing the egg from seizing into dense rubbery curds when it hits the center of a wok heated to high heat. Tossing the cooked grains and vegetables into this warm sauce binds the starch molecules of the quinoa directly to the fat droplets, producing a cohesive coating without requiring heavy reductions.
Efficiency and Yield Adjustments
Portion scaling requires careful volume tracking because doubling quinoa demands an exact 1:1.5 grain-to-broth ratio adjustment to prevent waterlogging. Leftovers retain structural integrity for up to three days when stored in airtight glass containers, provided the remaining chopped peanuts are packed separately to maintain crunch. Doubling the chicken component necessitates stir-frying in two separate batches to avoid overcrowding the cooking surface, which lowers pan temperature and causes steaming instead of proper browning.
