Seattle Stew is great tasting dish made from IKEA meatballs that have horse-meat in them. It could be eaten on the anniversary of the death of the famous racehorse called Seattle Slew out of either respect or disrespect.

Alternatively, if one opened a slaughterhouse for horses in Seattle, Washington, one could call stew containing horse meat Seattle stew.
I just ate some meatballs from IKEA and when I found out that I had done so I got to thinking about horses and then I remembered the legendary Seattle Slew. hence the name, Seattle Stew.
