But without refrigeration you may have concerns about food safety. One of the chief virtues of salamis and hard cheeses such as cheddars is also their energy density at @ 7 calories per gram – and lots of fat! There are some salamis which are labelled as needing no refrigeration. Some are rather large eg 200 grams for a single meal http://www.theultralighthiker.com/lunch-on-the-trail/ (though we have found them quite safe open for a few days at equable temperatures), some rather small such as our old standby Hans Twiggies @ 15 grams ea. At 50 grams per serve and in a number of delicious flavours these Wintulichs Biersticks may fit the bill and fill your stomach. They are available in the liquor departments of many supermarkets and also come more economically in a 1kg pack if you can find a stockist: http://wintulichs.com/product/beer-sticks-1kg/
