In a large lightly greased crockpot layer half of the tater tots then half the bacon pieces and half of the cheese.
Layer the chicken pieces over the cheese. Sprinkle the chicken with salt and pepper. Repeat the tater tots, bacon and cheese layer. Pour the milk over all. Cover and cook on low for 6 hours.
Notes the bacon provides a great deal of flavor and is perfect with the chicken and cheese. The tater tots will lose their shape and resemble hash browns so if you want to use the hash browns it will work wonderfully.
