Mexican Shredded Chicken Tacos- Crockpot Recipe

This Recipe came from a crock pot cookbook but I don't remember which one. Oops! I did happen to find a link with a similar recipe HERE but my recipe and modifications are below:

• 2 LARGE frozen chicken breasts
• 1 14 oz can of diced tomatoes
• 1 (tiny) can of green chillies
• 1 chopped onion
• 1 envelope taco seasoning 

Combine all ingredients cook on low for 6 to 8 hours.

Note: I used really large chicken breasts and it needed to cook for about 10 hours.

We added the mix to corn tortillas, shredded lettuce, low fat Greek yogurt, fresh avocado, salsa.
