If using fresh beans, clean beans and snip ends. Cook beans for 5-10 minutes in boiling water. Remove from boiling water and immediately submerge in icy cold water and let cool completely. Remove beans from water and dry. Toss beans with onion, oil, 1/2 cup vinegar, nutmeg and salt. Cover and chill at least 2 hours. Mix remaining 1 tablespoon vinegar with mustard and paprika. Add eggs and toss. Cover and chill at least 2 hours. To prepare salad, drain bean mixture thoroughly and toss in bacon. Layer in bottom of serving dish. Top with egg mixture. If desired, top with fresh parsley.
