I always like pickled beets and sweet pickles, or more particularly gherkins. Olives is one of the places where my hubby's keto diet and my son's vegan diet intersect -- there and mushrooms.
And yes, my cousins and I all did the black olives on the fingers as kids in the 60s and still as adults we have at least two cans of jumbo black olives.
At least in other years...
