I don't care how bad it sounds, the first place I would be jumping towards would be McDonalds or KFC. I would gorge. If I had trout food for that long, the fastest food possible would be the best food.
I'll save the more fancy ideas for later, once my taste buds have gone through the explosion of flavour that only fast food can truly provide.
Bow before the mighty Javoo!
