If you are worried about cooking, here is my advice ... get some dehydrated meals from Hawk Vittles. I love them. The pastas especially. It's great to have a meal that tastes like it was made in a kitchen after traumatizing your body and burning thousands of calories. All you need is some boiling water.

You can of course learn a lot more in the forums about backpacking cooking, but that is a no brainer to get you started.
