This is basically a "find the ingredients you like/want and dump them into your crockpot". There are so many options available for this recipe. I obtained it from a message board a few years ago.
1 package of boneless skinless chicken (we use boneless skinless thighs for variation and their lower price)
1 jar of salsa
A can of corn or 1 cup of frozen corn
And depending on if you like additional heat, you could also add a 4 oz can of chopped jalapenos or chilis.
Throw it all in the crockpot and walk away. Low 6-8 hours, High 4-6
Serve over rice, with cornbread, scoop it into soft taco shells.
Add cheese, sour cream, sliced/diced avacado, fresh salsa etc to taste before serving.
