Slow cooker chicken fajitas

First off, here is what you need:

Frozen chicken breast, onion, bell peppers (green & red), salsa, tortillas, various toppings such as lettuce, guacamole and sour cream.

Here is what I started off with. The salsa was homemade, of course! :)

Slice the bell pepper, chop up just enough onion to fill 1/2 cup and slice the rest up.

Place the chicken breast into the crock pot and add all of the other ingredients on top of that.

Cook on high heat for 5-6 hours. Stir every once in a while. 

After everything finished cooking, I shredded the chicken and placed it back into the slow cooker and set it on warm. Serve in tortillas with toppings of your choice.
