Burrito burrito

Yesterday I saw these in Tesco's.  So I ate one, and it was good.  So I ate another today.  After reading Born to Run, I thought they might be a viable candidate for my secret fuel, just as they are for those Tarahumara types - super high calorie, compact, tasty, reasonably resilient to squashing.



Then I turned it over and saw the ingredients - near on 80 seperate things!!!  Yes, that white box is almost entirely the intredients list.  I shall eat these no more.  However, some kind of improved homemade version...
