So my wife and I have been doing some experiments over the winter, trying different combinations to create our own menus for this summer's backpacking trips. The goal is to create meals that taste good, are very lightweight, and have a ton of calories. And ideally, they should be cheap, too!

Our average freeze dried dinner weighs in at about 6-8 ounces, and usually has about 350 calories or so per serving. It costs about $6-8, and is a bit big and clunky--we always repackage in baggies. That means they are about 100 Calories per ounce. And about a penny per calorie.

We want to beat those ratios.

Sound impossible? Maybe. But in working through the options, we found something that does a pretty good job of meeting all those criteria.

So check out the Slim Jim beef stick: 170 calories, and less than a buck.

That's 170 calories per ounce...and about 1.7 calories per penny.

Now we are curious. Can any of the foods in your backpack beat that?
