Combine eggs, soup mix, cranberries, bread crumbs and parsley in bowl. Crumble in ground beef. Mix. Shape into 1-inch balls. Arrange 12 to 14 meatballs on microwave-safe plate.
Cover with waxed paper. Cook on high for 3 to 4 minutes, or until no longer pink. Remove to paper towels to drain. Repeat with remaining meatballs.
Combine cranberry sauce, broth, brown sugar, ketschup, onions and cider vinegar in microwave-safe 2 quart dish. Cover and cook on high for 3 to 4 minutes, rotating once.
Gently stir in meatballs. Cover and cook on high for 1 to 2 minutes, or until heated through.
Note: I'm just not wild about cooking meat in the microwave -- so I prefer to do these the old fashioned way. I have good luck with placing the formed meatballs on a rimmed baking sheet and placing them in the oven set at 350 for about 10 minutes -- just until they firm up. I them add them to a saucepan on the stove that I have made the sauce in and let them simmer on low heat until they are cooked through.
