Spam definitely has a stigma in Asian cuisine and references hard painful times in history since WWII.  It symbolizes the American presence in Asian countries - how an American canned meat product made its way in dishes like Spam musubi and budae jjigae (army stew).  It’s hard to say where Spam fried rice first came from since there are Korean, Hawaiian, Filipino and Chinese versions.  Nonetheless, it’s Asian American (Canadian).  As a first generation Asian kid, my mom used to fry up slices of it, coat them in egg and put it in a sandwich for me for school.  The spam fried rice you find here, is a fusion of my own Chinese Canadian culture and my childhood memories.
