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! :-)
There are not many things that can beat the whole grain bread, unless it's 8 delicious little whole grain breadrolls ;-) These are perfect for breakfast, and you can easily prepare and bake them in one evening, for e.g. Sunday breakfast! :-)
My fool-proof recipe will be a great fun, and a good addition to your baking arsenal.
