Mix all other ingredients except for bread crumbs together in a medium mixing bowl.
Spread the cheese topping onto the chicken breasts.
Sprinkle with bread crumbs if desired. Cover and cook on high for 2 1/2 - 3 hours, low for 5-6 hours, or until the chicken has reached an internal temperature of at least 170 degrees F. I have found that the chicken has a better consistency when cooked on high.
Serve and enjoy!
Use a gluten free bread crumb or omit all together.
We have made this with good results substituting dairy free cream cheese and cheese alternatives.
Keep the carbs down by omitting or cutting back on the bread crumbs.
