Where do I buy a large amount of dried vegetables?
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.
