After extensive research (hey, someone has to do it!) I've narrowed it down to these two options from Tesco and Aldi (in other words those two shops are the ones closest to me). The Aldi version is 100g for 18p, Tesco is 65g for 20p--I'm sure you can guess which one I buy most often! Ostensibly the former is 2 servings per packet but does anyone really believe that? That ranks up there with the suggested serving size of cereals. With that settled, recommendations for GOOD Mexican or Tex-Mex in England would be very much appreciated!
