I'm thinking people store very different things in their refrigerators than I do (bread, potatoes, tomatoes/onions (unless cut)-- stuff like that never goes in my fridge. I would not be opposed to various forms of currency/money though!)
Mine:
Butter
Milk (I make myself a latte every day)
Beef (various cuts, but since it's magic, it will be the exact one I need--it would be nice to not have to buy beef once a year to fill the freezer, and the magic fridge would always have it thawed when I wanted to use it.)
Cheese (I love good cheese. Hell, sometimes I even love not-real-cheese-but-melts-well-processed-crap)
Bacon or dough (love bacon, love fresh bread. Bacon is expensive, but making dough takes effort... Not a clear winner for #5)
The rest I don't mind raiding the parent's garden for vegetables, then processing them to store in the freezer, or canning them (loving various pickled vegetables). Potatoes and stuff like that are cheap. Other stuff would be in the pantry or on the counter. The listed items are the more expensive of what I purchase or always want to have on hand.
