In a large bowl, combine the first six ingredients. Crumble bulk sausage over the mixture and mix well. Shape into 1-in balls. In a large skillet, cook meatballs over medium heat until browned, drain.
In a large saucepan, combine the cranberry sauce, vinegar, brown sugar, and mustard. Cook, stirring occasionally, over medium heat until cranberry sauce is melted. Add meatballs and sausage. Bring to a boil. Reduce heat; simmer, uncovered until the meatballs are no longer pink, about 10 minutes, and the sauce is slightly thickened.
