there's all kinds of great additions.....first, think of what you like best in BBQ, then think of how to add that in.....meats, cheeses, fruit type things, seafood....
The possibilities are endless
I'm thinking something like sliced marinated tenderloin steak, few chunks of fresh pineapple and a bit of teriyaki sauce and wrapped up in the bacon. Or idea #2 would be essentially pairing the bacon bomb stuffing with massive amounts of cheese all wrapped up. Or even something like a parmesan spinach and artichoke dip filled turd??
... oh man I need to go make some dinner before I pass out
