Season chicken breasts with salt, about 1/4 tsp. per chicken breast. Set the low cooker setting to "high".
Place chicken breasts inside the slow cooker. Add onion, jalapeño, and garlic. Sprinkle in ranch seasoning mix and black pepper, then pour in honey and hot sauce. Use tongs to mix everything together.
Cover and cook on high for 2 hours, or until chicken is cooked through.
Once chicken is cooked through, shred it directly inside the crockpot. Add butter, then turn heat to low. Toss the shredded chicken again with tongs, then allow the chicken to rest in the slow cooker for about an hour. Toss occasionally to continue coating the chicken in sauce.
Turn off heat, uncover, and let the chicken sit for about 15 minutes so the sauce thickens.
Serve on lettuce wraps, sliders, or whatever you please!
