I got this recipe at elk camp north of Bayfield, Colorado more years ago than I care to remember.While us 'manly types' were hunting, Gus, our camp cook spent his spare time fishing. He never ceased to amaze me with the things he hauled out the drawers and bins of his chuck trailer. In the middle of nowhere he had fresh spinach to make this wonderful dish. Until then the only way I'd had trout was breaded and pan fried. This was the start of my lessons in some of the better ways to prepare trout. The lessons haven't stopped since then, thank you very much.
