Cut each chicken breast in half so that you have two long and narrow chicken tender shape pieces.
Place bacon in a large skillet and cook over medium heat until about halfway cooked. You want some of the fat to cook off, but the bacon to still be pliable.
Immediately wrap a slice of bacon around each chicken piece while the bacon is still pliable. Place in crockpot.
Add onion to skillet and cook in bacon fat for 2 minutes. Remove with a slotted spoon and place in crockpot.
In a medium bowl, whisk together both soups, sour cream, flour, and garlic powder. Pour over chicken.
Cover crockpot and cook on low for 5-6 hours, until chicken is completely done.
Remove chicken from crockpot and place on a serving platter. Whisk the sauce well and taste for seasoning. Add salt and pepper to taste.
Serve over rice, egg noodles, or mashed potatoes.
Notes
Newer slow cookers run hotter then older ones. If you have a newer one, your chicken may be done in less than 5 hours.
