I've done these a few different ways. One of my favorites is to simmer diced mushrooms and garlic in some good olive oil. Then mix it with the cream cheese. I'll add a little habenero chili powder and smoked paprika. Mix it all up good and stuff away.
Some great ideas I will definitely be trying in the above comments. I have only ever done them on the grill, but I always do in halves, stuffed with a mix of italian sausage(fried beforehand), cream cheese, aged cheddar and parmesan and wrapped in either thinly sliced bacon or sliced prosciutto.
I have been thinking about mixing it up by using some ground venison and spices and trying a batch on the smoker
