If using steak strips, follow same instructions as sliced pork in Steps 2 and 5, stirring occasionally until no pink remains and steak strips reach minimum internal temperature, 4-6 minutes. Rest, 3 minutes.
If using whole chicken breasts, pat dry, and, on a separate cutting board, cut into 1” pieces. Season with a pinch of salt and pepper. Follow same instructions as sliced pork in Step 5, stirring occasionally until chicken reaches minimum internal temperature, 5-7 minutes.
