01 - Preheat the grill or barbecue to medium heat.
02 - In a mixing bowl, combine tomato ketchup, apple cider vinegar, brown sugar, Worcestershire sauce, Dijon mustard, smoked paprika, garlic powder, and black pepper. Whisk until smooth.
03 - Arrange sausages on the grill. Cook for 10 to 12 minutes, turning frequently to ensure even browning and thorough heating.
04 - During the final 5 minutes of grilling, brush sausages generously with the prepared BBQ sauce, rotating often to glaze and caramelize all sides.
05 - Serve sausages hot, in buns if desired, with extra BBQ sauce and your choice of sliced onions, pickles, or coleslaw.
