Slice each chicken breast horizontally into 3–5 thin, even cutlets and pat dry with paper towels.
In a large bowl, whisk together cornstarch, paprika, 1/2 teaspoon garlic powder, onion powder, and salt.
Add the chicken to the seasoned mixture and toss to coat; drizzle in the soy sauce and olive oil and toss again until evenly coated.
Arrange the chicken in a single layer in the air fryer (cook in batches if needed) with space between pieces and air-fry at 400°F for 9–12 minutes until lightly charred and the internal temperature reaches 160°F; let rest 5 minutes, then slice or dice.
While the chicken cooks, heat a small pot over medium and whisk together the butter, hot sauce, brown sugar, and the remaining 1 teaspoon garlic powder until butter melts and the sauce is smooth; remove from heat.
Prepare quinoa or rice according to package instructions and, if using, make quick slaw and pickled red onions.
Divide quinoa or rice among bowls, top with sliced chicken, drizzle buffalo sauce to taste, and finish with quick slaw, pickled red onions, and Green Goddess sauce.
