Mix the pork, liquid smoke, salt and pepper thoroughly in a bowl. Divide the pork into two even balls, then roll them into logs. Press the logs into approximately 1/2-inch thick ovals on the cutting board. Use your index finger to indent them evenly crosswise, to mimic rib bones.
Heat a grill pan over medium high heat, or preheat your gas or charcoal grill. Grill the patties for 5 minutes per side, brushing each one with 1/2 tablespoon of barbecue sauce after you flip them. Once both sides are done, allow them to cook for 1 more minute per side to caramelize the sauce, then remove and prepare your sandwich assembly.
For the Chaffles
Whisk all ingredients together in a small bowl. Preheat your Dash, then pour 1/4 of the mixture onto the surface, spreading it to the edges before closing the lid. Cook for 3-5 minutes, until golden brown, then remove with a fork and repeat with the remaining mixture until you have four chaffles.
For the Sandwich Assembly
Brush another 1/2 tablespoon of barbecue sauce on the inside of the top chaffle bun for each sandwich. Stack the patties on the bottom buns, then top with slivered onions and pickle chips before placing the remaining chaffle buns on top, barbecue sauce down.
