Where do I buy a large amount of dried vegetables? I'd like to buy a large amount of dried vegetable matter to stock up on backpacking supplies.  I'm interested in almost any kind of edible vegetables, including the generic, assorted, mixed, ground-up, and processed kind.  I'd just like to have a lot of options to look at, but CHEAP above all! Wholesale retailers are also of interest to this OP.

And why vegetables? For flavor, fiber, and vitamins.
Do you have a food co-op or health food store near you? Lots of them sell in bulk, including dried veggies or dried mixes (for example refried beans or falafel). Additionally, you can ask if they offer a case discount, which means you buy a 20-or-so pound bag and sometimes can get about 10% off the bulk rate. To see if you have a co-op in your area check coopdirectory.org
