I'm looking for simple, savory snack ideas/recipes for the refreshment area of my salon.  I have sweet covered - cookies are always an easy staple, but savory things that don't spoil or cost a fortune (in money and time) to make? Any ideas?

a little more information:  There's no refridgeration in the refreshment area.  There is a refridgerator in the back so snacks could be stored there until ready to be set out and there is someone available to refresh the table.  Everything has to be 100% vegan, but no other restrictions.  These should be small, we're not serving lunch, just a quick snack for people spending a couple hours at the salon.
