Moms who work out of the house - what do you typically do for lunch? Do you bring a lunch? Order in? Something else?

I want to bring a lunch but I usually don't. I either grab sushi from the place next door or order in with co-workers. I think my New Year's resolution should be to try to cut down on buying food daily, it adds up! I'm sure I could save some serious cash by bring a lunch.

What do you do?
