Have a Bento Lunch (Explained)

So I've been interested in Japanese/Asian culture for a while now, probably from reading too much manga but that's neither here nor there, what is important is the awesome stuff they have! One of the things that jumped out at me was their lunches, which contain a range of different foodstuff (though usually contains at least one rice dish) put into small segments into a bento box, pauvaisvo:

To do this though I need two things:
1. A bento box
2. Created food to put into said bento box

Easy enough right? We'll see...
