Spray a 4-quart slow cooker with cooking spray. Place the chicken breasts in the slow cooker, then top with buffalo sauce. Sprinkle with ranch seasoning and drizzle with oil.
Cook on low for 6-8 hours. Once the chicken is tender, remove and shred. Return to the slow cooker.
Serve in lettuce wraps, low carb tortillas, or with a salad.
Notes
Each serving is approximately 3/4 cup shredded chicken and has 0.2 total carbs.
