I hate it, but in this day and age I'd never put something called "fatty sliders" on a menu. Some numbskull would decide it was offensive.
ABTs are good but in a restaurant setting they might be tough to turn around quickly as an on-demand appetizer. There's also the question of the labor cost involved and the time used in the smoker vs. what people would be willing to pay for them.
Smoked Sausage link, maybe served with a chunk of cheddar.
BBQ Nachos, tortilla chips, pulled pork, cheese, jalapenos, maybe some slaw, sauce
Brunswick Stew (great way to use extra meats)
Redneck Lasagna (brunswick stew over mac&cheese, sometimes wtih a little more pulled pork added)
