This dish would not have been created without the inspiration of Mirjam, Bill, Mysterygirl, bratty 1, leeannr, Miller, SueL and Karen in Colorado. They all offered advice and ideas, and pointed me towards recipes as I attempted to create a dinner with some corn tortillas I had on hand. This is the concoction I came up with (and it was not what I went into the kitchen to create, but this dish kind of created itself as I went along), after reading all the recipes and considering all the advice; thanks to you all!
