Stoveless meals are those that do not require cooking (no stove). In most cases you just need to add water and wait until the meal is rehydrated. Usually a waterproof container either brought commercially, or in the spirit of the stove less movement, an empty peanut butter jar works well to ‘cook’ your meal in.
A ‘stoveless’ meal rehydrated in a 500gram peanut butter jar. Just add water and wait for about 90 minutes; no cooking required on the trail. I will add the water at breakfast time just before I head off for the morning and the meal is ready in time for lunch.
