Whether using a single burner backpacking camp stove, or a campfire (where permitted), the “just add water” feature of most freeze-dried meal options makes them easy to prepare. The worst that can happen is burning it or boiling over. Some options don’t require any cooking at all! But between meals, when you need a boost, snack bars tailored for high-endurance activities can keep you feeling full. Look for lightweight options that are available in different flavors, so you don’t have to eat the same thing day after day.
