That's a favorite here around town too. I find that most folks hosting parties have a concoction similar to this. We call it Buffalo Chicken Wing dip.
My recipe is this:
1 block of cream cheese
2 cans of Chicken breast meat
1 cup of shredded sharp cheddar
Syberg's (local STL joint) wing sauce and Cayenne pepper sauce, both to taste.
Mix everything then place into casserole dish. Add more shredded cheddar on top to cover. Bake at 350 until top cheese is melted and golden brown around the edges.
Its always a home run
