What do you have for lunch?

Be an idea invest in an electric lunch box.
About £25 on Amazon
Plugs into cigarette lighter socket or what ever you call it these days
.
It basically warms up ready cooked pre cooked meals.

Just plug in and leave for. Few hours or more depending on what’s in it and you have a warm.meal when you stop.
