In a large saucepan, combine the cranberry sauce, BBQ sauce, soy sauce, mustard, honey, salt and orange zest. Warm over medium-low heat, stirring, until everything is combined. Bring to a low simmer and allow it to bubble gently until slightly thickened, 5 to 7 minutes.
Add the sausages to the pan and stir. Allow the sausages to warm through, about 5 minutes. Transfer to a chafing dish or warming dish. Serve with toothpicks on the side.
