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 thoroughly blended.
03 - Arrange sausages on the grill. Cook for 10 to 12 minutes, turning frequently with tongs, until the sausages are evenly browned and fully heated.
04 - During the final 5 minutes of grilling, apply the prepared barbecue sauce generously to each sausage using a basting brush. Rotate sausages to evenly caramelize all surfaces.
05 - Serve sausages hot in buns if desired, with extra barbecue sauce and favorite toppings such as onions, pickles, or coleslaw.
