Crockpot Mexican Chicken

2 - 2 1/2 lbs. boneless, skinless chicken breast
2 cans diced tomatoes with chiles
2 packets of taco seasoning

Spray crockpot with cooking spray and put chicken in. Mix tomatoes and seasoning and pour over the top. The original recipe calls for frozen chicken, and to cook for 6-8 hours on low. I use fresh/thawed chicken and cook on low for about 4 - 4 1/2 hours. When the chicken is done, shred and serve on tortillas with cheese and sour cream.
