This is my favorite meatballs recipe to date. It's spicy, it's rich, it's deliciously thick and serves as a complete meal on it's own. It's one of my never failed meals, because it's impossible to make it taste bad, it can even survive burning (a bit :P), wrong order of cooking, missing ingredients and virtually any cooking disaster you can imagine ;-)
Bento is not only rice, but also other ingredients, like... pasta. This recipe came to life when I had some uncooked beef left-overs and just wondered what to do with them. Cooking them as a part of bento was a great idea!
