German-Style Pickled Eggs

In a large saucepan, combine the first eight ingredients. Bring to a boil. Reduce heat; cover and simmer for 10 minutes. Cool completely. Place onions and eggs in a large jar; add enough vinegar mixture to completely cover. Cover and refrigerate for at least 8 hours or overnight. Use a clean spoon each time you remove eggs for serving. May be refrigerated for up to 1 week. ');
