Crock Pot Chicken (Or Pork) Fajitas

Edited to add: I just made these again last night using 1 lb of pork stir fry strips instead of chicken and it turned out great! Very flavorful. I stirred in an extra TBS of taco seasoning an hour before it was done based on the other reviews but I'm not sure it needed it. I would suggest maybe only adding the extra taco seasoning if your chicken breasts are large or you're using more than a pound of pork. These are really easy to make and taste Great rolled up in warm flour tortillas with all the usual fajita toppings.
