I'm 100% behind the Vegetarian cookbook authors when they say "make your own bars, brother". Their preparation lists a brief "oatmeal, barley and wheat flakes and nuts of your choice" as its primary guide to the complex world of muesli construction which is kind of weak sauce. I love this cookbook but detest some of the lazy steps that it takes which unecessarily cloud a kitchen under a bottle of, say "pumpkin pie spice" and not of its reagents which are probably also required to held in fresh quantities.
