Chicken takes a cue (or is it BBQ?) from pork and gets fork-tender, shredded and piled onto a crunchy roll. Eat it hot while the cheese is good and melty.
I don't like using Cheese Whiz in casseroles, so I wouldn't make this until my sister-in-law served it one night. No Cheese Whiz, just real cheddar cheese. Delicious, and kid-friendly.
