A favorite easy salad.
Preheat oven to 425 degrees F (220 degrees C). Spread chicken onto a baking sheet.
Bake chicken in the preheated oven until cooked through, 20 to 30 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
Put lettuce in a large bowl. Whisk milk, sour cream, and ranch dressing mix together in a bowl until smooth; add to lettuce and toss to coat.
Cut cooked chicken into small pieces and toss with barbeque sauce in a bowl. Mix barbeque chicken, kidney beans, corn, and tomato with lettuce.
