Directions

Cut sirloin steak into bite-size pieces. Place steak in crockpot with chilis, soup mix, and water and cook on LOW for 6-8 hours.
Slice onion and green pepper into strips and saute in olive oil.
Take meat out of crockpot (I use a slotted spoon) and place meat, onions, green peppers, and whatever other toppings you like on your fajita (I listed what we put on them, but you can usewhatever you like).
