This casserole is simple and delicious, and makes a perfect snack during a picnic (bento anyone?)—you should use it as a basic idea for a casserole, since the pasta sauce is the stable and the most important piece of the meal. It's also a very tweak-able recipe! :-)
I always wanted to make these, and finally got the guts — oh boy, I wasn't really prepared for the amount of nitty-gritty with making these. I started with original German recipe that called for 500g of almonds, but that ended up being 2 full baking sheets and lots of sneaky snacking between steps ;-) But the result is good, and these cookies are worth the effort.
