They’re back! Or maybe they never left. But I haven’t seen olive-stuffed cheese balls in decades and now I’ve baked multiple trays of this marvelous 1950s hors d’oeuvre. I spotted the recipe recently on another blog, A Well-Seasoned Kitchen, and it almost made me tear up. My mother, an unapologetic non-cook, had only one party appetizer in her repertoire and this was it.
