This sounds good for any time of year. It does seem to be a good dish for a retro holiday buffet or winter festive meal in the south.
Keep in mind the French Dressing, is not the French Dressing of the bottles found in the store but more a vinaigrette. Don’t miss the note about the slightly different procedure if you want to use mayonnaise.
Combine sweet potoatoes, celery and salt. Add dressing and toss together lightly until all potato is coated. Either kind of dressing is good. If mayonnaise is used*, marinate the potatoes half an hour in French dressing in a covered bowl in refrigerator, then drain and add mayonnaise. Serve in lettuce cups. 5 servings.
