I feel tossing together some basic meal is so simple I can't bother to go pick anything from outside even though I live in the middle of great restaurant concentration. A bit of frozen veggies heated on pan, with pasta or couscous on the side. Takes literally ten minutes and costs less than one euro.

Or a large casserole that takes an hour to cook but gives eight portions. Quick heat-up for lunch during the week saves time too, and you stay in control of the salt intake unlike with ready meals. So cheaper, healthier, faster. Downside is that those meals are pretty basic and repetitive, but then again eating out feels a bit more special if you don't do it every day.

I do cook "real" recipes too with more steps and more flavor, but only with my partner as I don't care to do it just for myself for weekday meals.
