Instead of using the rice crispies cereal and granola just toast some plain Irish Cut Oats (uncooked of course) in a 300 degree oven for 20 minutes to give them a little crunch.
You can also add in any type of dried fruit (cranberries, dates, figs), crushed up nuts, and some dark chocolate chunks.
A few good soy-free chocolate brands found at Whole Foods are Pure Icelandic Chocolate, Alter Eco Fair Trade Chocolates, Equal Exchange Chocolates, and Navitas Naturals Organic Raw Chocolate Nibs (warning- this particular one does not have any sugar in it so if you eat it by itself it is extremely bitter).
These are a great snack that you can take with you anywhere!
