Those shirts are adorable and made me laugh.

Cooking for one is a challenge. When I was still cooking a lot, I would cook a full meal as if 4 or so people were going to eat. Then I would eat a full meal and put the rest in the fridge and have leftovers for days. That is when I packed my lunches for work. I didn't eat the exact same thing each day, but would use at least part of the leftovers and maybe add in something new each day. It worked famously for a long time. I don't mind leftovers at all. If I liked it the first time, I like it later too.
