Ultra-Thin Biscotti/Biscuits/Crackers Recipe?

Hi All,

I've really been enjoying these super thin "biscuits" sold at Whole Foods. (Brand name: daelia's.)  They come in varieties such as "Hazlenut-Date" and "Walnut-Raisin".  They're really a hybrid between a cookie/cracker/biscotti.  In fact, I believe I've seen similar things sold as "crackers." Usually in the cheese section.  They're great with cheese (obviously;) and like most biscotti, don't include butter or oil in the ingredients.

I would love to recreate these at home, using at least some flours that aren't all white, but can't seem to figure out the precise method. They're very similar to biscotti, just much thinner.  Whenever I've made biscotti, I've found that you can't slice the dough too thin after the first bake or it crumbles.  Has anyone come across a recipe for something like this?  Or have suggestions on how to achieve a similar cookie in my own kitchen?

Thanks!
