01 - Preheat grill to medium heat, approximately 350–400°F.
02 - In a small bowl, whisk together the barbecue sauce, honey or brown sugar, Dijon mustard, apple cider vinegar, smoked paprika, and black pepper until evenly combined.
03 - Place the sausages on the preheated grill. Cook for 10 to 12 minutes, turning occasionally, until evenly browned and nearly cooked through.
04 - Brush the sausages generously with the prepared BBQ sauce mixture. Continue grilling for an additional 2 to 3 minutes, turning as needed, until the glaze is caramelized and the sausages are fully cooked through.
05 - Remove the sausages from the grill and let rest for 2 minutes to allow juices to settle.
06 - Serve hot, garnished with fresh parsley, and accompanied by soft rolls, sliced onions, and pickles if desired.
