Then, place chicken breasts on the bottom of the slow cooker.
Next, sprinkle garlic powder on top of the chicken.
Then, pour salsa on top of the chicken. It's o.k. if some of it falls off the sides.
Add olive oil on top of salsa and cover. Cook on low for 4 hours.
Make ahead instructions:
Make ahead by putting all the ingredients into the slow cooker ceramic insert and placing it in your refrigerator the night before. Or, if you don't have room in your refrigerator, place all ingredients in a one-gallon zipper plastic bag and dump into slow cooker when ready to cook.
