If using whole chicken breasts, pat dry and cut into 1" dice. Follow same instructions as diced chicken cooking until chicken reaches minimum internal temperature.
If using pulled pork, coarsely chop. Follow same instructions as diced chicken in Step 1, stirring occasionally with 1 Tbsp. water, breaking up pork, until pork is warmed through, 1-2 minutes. Excess pork fat will render while cooking and add flavor.
If using steak strips, separate into a single layer and pat dry. Follow same instructions as chicken in Step 1, cooking until no pink remains and steak reaches minimum internal temperature, 4-6 minutes.
If using Impossible burger, follow same instructions as chicken in Step 1, breaking into smaller pieces and cooking until heated through, 5-7 minutes.
