Pat the chicken or pork dry and cut into 1/2 thick strips. Place all the cut meat into a medium or large resealable freezer bag.
Combine all shawarma seasonings together in a bowl. Add 2 Tablespoons of the mix to the bag and toss until the meat is completely coated in seasoning. (If you prefer, you can do the mixing in a bowl before adding to the bag.)
Remove the excess air, seal, and freeze. Place the rest of the seasoning in a medium sized resealable freezer bag and store in the freezer to maintain its freshness.
On the day of cooking, take the bag of shawarma out of the freezer to thaw.
Place the 2 Tbsp. of oil in the Instant Pot and select the Sautee setting. Place the chicken or pork in the Instant Pot to sear for about 2 minutes.
Turn off the saute setting and add your broth or water.
Select the meat setting for 10 minutes. You can use the natural or quick release.
Spread a layer of hummus on a pita, add some of the cooked meat, top with some dill pickle slices, and sprinkle with a bit of parsley. Roll the pita and get to the eating!
