Yes!  Just like my [One Minute] Instant Pot Freezer Prep Taco Meat, you can make extra of this chicken to freeze!  I always make a double batch and use my Souper Cubes to freeze a second portion for another night. To reheat your frozen taco filling, simply place 1/4 cup of water and your frozen taco meat into your Instant Pot and set it for three minutes.  The instant pot will do all the work for you!
