This simple recipe requires only 3 ingredients: sliced pork loin (already mentioned minute steaks or easy steaks), shallots and teriyaki sauce. It's also one of the lazy recipes — part of it you can prepare evening before, and finish it quickly before serving or packing your bento box. Plus, marinating for a long time allows increased flavors to transfer easily across the meat!
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!
