So why is food ever an issue if you're a wizard? Why would Lupin ever 
*not* have a square meal? Why would Sirius be starving in a cave with 
Buckbeak, waiting for deliveries from Harry (he'd have a wand by 
then, too, or at least the use of Harry's)? The magical availability 
of foodstuffs would go a long way to explaining the Weasley family 
economy (lord, feeding that family!). But we don't see the magical 
creation of packaged "brand" foods (Cribbages Wizarding Crackers, 
sweets, etc.). Thoughts?

My guess would be that Minerva is not materializing food out of thin 
air, she is retreiving it from the school's kitchen; and Molly is 
using magic to help her cook her food.
