Preheat the oven to 400°F. Bake 2 pounds of boneless, skinless chicken breasts for 15-20 minutes until cooked through and juices run clear. Allow to cool completely.
Shred or chop chicken into small bite-sized pieces. Place in a large mixing bowl. Chop 1 cup celery and 1/2 cup red onion. Add to the bowl with chicken. Add 1/2 cup crumbled blue cheese and 1/3 cup buffalo wing sauce. Stir to coat chicken and vegetables.
In a small bowl, whisk together 1/3 cup ranch dressing, 1 tablespoon fresh lemon juice, 1/4 tsp salt and 1/4 tsp pepper. Pour over the chicken mixture.
Add any other desired mix-ins like shredded carrots, bacon bits, etc and fold ingredients together until fully mixed. Taste and season further if needed.
Line plates or bowls with lettuce leaves. Use an ice cream scoop or spoon to portion chicken salad on lettuce.
Top servings with shredded cheddar cheese, wonton strips, and ranch or blue cheese dressing. Eat immediately or refrigerate in a sealed container for up to 5 days.
Customize by adjusting the spice level with more or less buffalo sauce or using different dressings. Swap ingredients to cater to dietary needs and personal preferences. This versatile salad also makes an easy meal prep recipe for healthy lunches to go!
