For those of us of a "certain age," Joe Carcione WAS the expert that you checked out before buying produce. Long before it became popular, he recommended that we "keep it simple." He was at the produce market every day at 4 AM (@!) and we always knew that whatever Joe recommended was checked out in person.
Before there was South Beach, Joe advised us to cut down on the carbohydrates and fat. His "Joe Carcione Special" consisted of shredded cabbage in place of pasta, sauteed with onion and garlic, and topped with marinara sauce and grated cheese.
