For the chicken, in a medium bowl, combine the chicken, oil and spices. Use right away or marinate in fridge for up to 24 hours (or freeze).
Make macaroni and cheese according to package directions.
Heat a large heavy-duty non-stick pan to medium-high heat for 2 minutes. Once the pan is hot, coat the plan with a light drizzle of oil and cook the chicken for 3 minutes per side or until charred and cooked through. Serve on top of prepared mac and cheese. Sprinkle with parsley if desired.
