Make stew over a fire in less than 2 hours.
It depends on the recipe. The vegetable stew I usually make takes about an hour to cook, as all the ingredients are relatively quick cooking. In two, that'd give time for getting the fire going. That said, I wouldn't volunteer to make it after a hard day travelling.
Make stew over a fire in less than 2 hours.
I think I'm going to add a scene in my WIP where a character makes 'stew' while traveling and somebody critizises it, leading to an entire discussion about the difference (and whether one even exists) between soup and stew.

This kind of bugs me. Isn't the stew thing really just a matter of semantics? ... what else are characters going to call "a bunch of ingredients cooked in a pot"?
If heroes are traveling light and on foot (as they often are) why would they carry around a heavy piece of iron cookware just so they could eat something brothy? The extra weight and just setting the pot up over a fire seems needlessly complicated for a group on the go.
That's what horses/ponies are for. And a giant iron cauldron isn't exactly necessary. A turtle shell works well (though probably just as cumbersome and still kind of heavy). You can also use an animal stomach as a sort of pouch to cook in - similar to the modern hobo stew cooked in tin foil. Not too difficult to carry or find. Again, it's not gourmet but it's food - and technically it's stew.
And on top of that it makes for some fun imagery.
Personally I'd like to see some fantasy adventurers head out on the road with their beloved nanny goat. Cause, you know, milk is good for your bones and stuff. Plus pack goats can carry quite a bit, and browse as they walk so don't need to stop and eat like horses do.
I have a goat!! I have a goat!! 
Depends. Are you a fan of breaking teeth on a bit of meat that so tough you could use it as a brick?So making a 'stew' with water instead of gravy in an hour seems pretty reasonable. .

Something you should do is read Diana Wynne Jones's Tough Guide to Fantasyland. Covers pretty much every cliche in the book, and is damn funny.
A personal peeve of mine is the travelogue story, where the heroes inevitably wind up traveling to every corner of the world like clockwork, picking up denizens of each place along the way . . . looking at you, David Eddings.
