Split pea soup was a healthy food originating from Earth. Kyle Riker had his own recipe for split pea soup which he prepared for his son, Will. Will recalled that the soup helped to keep him warm on those cold nights in Alaska.
In 2368, Will replicated his father's split pea soup for Soren to try. The J'naii found the soup tasted "unusual", but thought it pleasant. (TNG: "The Outcast")
