Dehydrated hamburger meat. Probably the best thing my grandma could have ever sent me. It makes Ramon Noodles not too bad, and allows for the purchase of Hamburger helper's and mac and cheese with meat in it. I'm pretty sure, all she did was cook the meat until it was completely dry, then throw it in dehydrator.*spelling.
All I have to do is let it soak in hot water for about two minutes, then add it to any dish I'm making. It turns back into regular edible-ness and makes life a little more fantastic.
It's also pretty great for storage, as long as you put it somewhere where it can't get ground up even more. (My last batch was pretty much dust.) So that's my gift numero uno for the broke college kid. Yayy College.
