For some reason, watermelon comes to my mind. Or perhaps mixed melon balls? It wouldn't compete with the intense flavors of the wings and sauce, and would have a cooling effect on the heat from the peppers.
If you want cheese, I think I remember a TV chef using feta cheese with watermelon in a salad. He put pepper on it, too. Don't know about that.
