There is also MRE packs of PB and several jelly varieties. since there are various companies making them they vary a little in the ingredients. the PB like all MRE items is 'fortified' with vitamins. Some have sugar and hydrogenized oil, like Skippy, and I've seen one with just peanuts, oil and salt. the the PB's are 1.5oz pkts, usually sell for around 45cents, the Jelly and Jams are in 1 oz pkgs and usually sell for around 35 cents.
