College go-to:  Hot Pockets
Adult upgrade: Amy's Vegetable Pie in a Pocket Sandwich or Spinach Lasagna

College taught you well. You can eat virtually anything that comes out of a freezer as long as you heat it first; its owner and the length of time spent in the freezer are trivial details. Now that those dark four years are behind you, and you only have one roommate, when all their Hot Pockets have dissapeared there will only be you to point fingers at. Instead, buy your own meals and opt for one of the healthy, frozen options from Amy's Kitchen. Bean burritos, FTW!
