I bulk prepare and freeze food often for those situations, so I can get lazy and still have a decent meal. For example, my freezer currently has chickpeas stew with sausages, kibbeh, Bolognese sauce, a simpler tomato sauce, a half dozen pierogi… all of those can become a meal if paired with quick stuff, like rice or pasta and a tossed salad.

If that fails, I cook some quick polenta using pre-cooked cornmeal, then break some eggs in it.
