I am not sure on the availability of these kinda things (I will list shortly) in your area/country or the price for same but my thoughts are, if they are nuts, seeds, grains, whole grain, fruits, vegetables, then they will be sufficient, varied and quite beneficial and filling to use. These, when incorporated with exercise, sunlight, fresh air and water:
Sunflower seeds
Peanuts (raw or roasted)
Cashew
Punkin Seeds
Corn
Beans
Peas
(May be mixed, blended or eaten raw)

Whole grains (rice, oats, hominy, barley and Bulgar)
Raisins
Orange
Grapefruit
Apple
