In a large mixing bowl, add lemon, taco seasoning, salt and garlic to cubed chicken breasts and mix until chicken is smothered. You can add more garlic or lemon if preferred.
In a large sauce pan sautee chicken until brown (but don't overdo it!)
Add all other canned ingredients and salsa to crock pot with chicken, mix it all together and cook on high for 3 hours. Turn to low for another 2 hours.
