Everyone's got different standards for healthy, and cheap. Mine probably aren't great, but I think it's a good starter position for going down this road. Especially if you're not really a cook.

Here's mine: hit the grocery store and pick up some freezer ziplock bags and some family-size packs of meat (whatever's on sale). Individually bag and freeze them. With some veggies and sauce (A1 goes well with a lot), you've got some good options.

Also, pasta. Mix in some chicken.
