On these unexpectedly late nights I turn to my personal freezer section. I usually have something stashed away in there that can be quickly re-heated and eaten for dinner - that last cup of soup that I froze before it went bad, a bag of Chinese dumplings, some tortellini that can be made into a fast soup with a can of broth.
Basically, anything that requires zero thought to make and then put into my mouth is a candidate for a 9pm desperation dinner. Even a giant bowl of popcorn or a can of warmed beans on toast will do the trick when we're hungry enough!
Do you have a plan for nights like this? Or do you wing it from whatever you can scrounge from you freezer or cupboards?
