>>519597Theres many outdoor shops in Reykjavik with dehydrated meals, but they are comparatively expensive, if you can, buy them at home and bring them with you. Best /out/ food in Iceland is hardfiskur, dried fish, really light, endless shelf life and 83% protein. Also buy some of their rye bread as an iron ration, you can life of one pack of fish and one loaf of bread for 3 days. Bring some tea bags and sugar, a hot tea really makes the difference on a miserable cold, wet and windy day. Also a good dose of granola/chocolate bars, you will need to carry a shitheavy pack and shelter is really rare, so if you can hide behind a rock and just grab in your side pocket and snack is gold.
