01 - Preheat the grill or barbecue to medium heat.
02 - In a mixing bowl, whisk together tomato ketchup, apple cider vinegar, brown sugar, Worcestershire sauce, Dijon mustard, smoked paprika, garlic powder, and black pepper until fully combined.
03 - Place sausages directly on the grill. Cook for 10 to 12 minutes, turning frequently to ensure even browning and to heat through.
04 - During the last 5 minutes of grilling, brush sausages generously with the prepared BBQ sauce, turning to caramelize all sides.
05 - Serve sausages hot, in buns if desired, accompanied by extra BBQ sauce and preferred toppings such as sliced onions, pickles, or coleslaw.
