Warr Shu Gai or Almond Boneless Chicken, like chop suey, is a Chinese-inspired American dish. So far as I have been able to determine, it originated in Detroit. It was a favorite dish of my childhood there. Every Cantonese restaurant in the area serves it, but I've never been able to find it outside of Michigan. Descriptions of it to Chinese restaurant personnel elsewhere have been met with blank stares.
