The Lunch Thread - What do you get for lunch?

I’m so hungry…

Do you buy stuff everyday at wherever? Doing so tends to accumulate on your food bill and you may not be eating the best food or you may be forced to eat what’s available depending on your location.

Eating sandwiches is good and cheap but gives me food coma and I don’t like all those preservatives.

What do you eat for lunch or do you have any suggestions as to what one should for lunch?
