One Bento, Cakes, Side dish, and Snack recipe with Beef, Spinach, and Tomato paste made by Boiling, Kneading , and Rolling

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!
