Buffalo Chicken with Blue Cheese

~4 boneless chicken breasts cut into chunks
~16 ounces cream cheese (light is fine, but not fat free)
~1 (12 ounce) bottle blue cheese dressing
~1/2-3/4 cup hot sauce
~8 ounces sharp cheddar cheese

Place the cooked chicken in a large baking dish. (For a party, I usually use the disposable aluminum pans)
Pour your desired amount of hot sauce over the chicken, and season with salt and pepper if desired.
Set this dish in the refrigerator to let the chicken absorb the flavor.
Preheat your oven to 350.
Next, over medium heat in a large pan, melt the cream cheese. (If you are pressed for time, cream cheese can be melted in the microwave.)
Pour in the blue cheese dressing and stir until they are completely combined.
Pour this mixture over the chicken.
Bake for 10 minutes and remove, but don't turn the oven off.
Sprinkle the cheddar cheese evenly over the top and return to the oven for another 10-15 minutes, until the cheese is melted and starting to brown just a little.
Serve with celery sticks
