Use a small lightweight bowl and a digital scale to make portioning meals easy, especially since many dehydrated foods are tough to accurately measure with cups/spoons. A 100-gram meal is usually sufficiently filling for an average hiker, and 150 g is satisfying for a large or very hungry hiker. Aim for a ratio of ⅓ protein, ⅓ starch, and ⅓ sauce/vegetables, etc. for a total of about 100-150 grams.
