Okay - maybe this doesn't exactly qualify as a bento - but while staring at the scraps in my fridge, it suddenly dawned on me that I had the ingredients to try making gyudon (beef bowl) - except for dashi. But since dashi generally makes me nauseous, I thought I could try substituting soup broth and see how it came out.
In went my leftover teriyaki sauce, 3/4 an onion, my substitute soup base, and some thinly cut rib-eye steak . . . and then I remembered the leftover carrot stars in the fridge. Tee hee!
Om nom nom!
Yes. I need professional help.
