Resource management.

Looking around the kitchen cabinets and what passes for a pantry, wanting to supplement a half-meal's worth of pasta, thinking about what's readily available. Some cherry tomatoes came my way, a couple onions didn't get used in last week's rice dish. There's sardines. There's an impulse buy can of kidney beans.

With one thing and another, there's tomato-sardine-bean soup that manages to do the trick and then some. Sardines and beans - affordable luxury.
