Boneless wing ideas
You could make your own pepper sauce, just use mild peppers instead of hot ones. That way they will look like traditional buffalo wings, but won't have all the heat.
Pressure cook the peppers in some cider vinnegar along with a few cloves of garlic for a few minutes. Then pour it all into a blender, and blend it. Lastly, run the sauce through a metal strainer to remove the skin and seeds.
Then just mix the sauce with some melted butter and toss your chicken in it.
There are also a number of recipes for sweet & sour sauces too - such as mixing apricot preserves with some spicy brown mustard and a little garlic powder.
