Cut the chicken breasts into cubes and put them in the crock pot.
Sprinkle with taco seasoning.
Add salsa and stir to coat.
Top with corn, black beans, rice and chicken broth, gently stir these 4 top ingredients, leaving the chicken on the bottom.
Cook on low for 3 1/2 hours, stirring the top layer after 2 hours.
After 3 1/2 hours, stir everything together and check to see if the chicken is fully cooked. Continue cooking for an additional 30 minutes, if necessary.
If there is too much liquid, leave the lid off for the final 20-30 minutes.
Note: Adding the rice to the crock pot makes it soft and a little mushy. If you are super picky about your rice, leave the rice and broth out of the crock pot and cook your rice separately.
