Take your lunch.

Whether you are going on a play date with kids or to work or the zoo, consider taking your lunch. Lunch out is almost guaranteed to be more expensive than taking your own lunch. If you plan your dinners well enough to always feed double, everyone in your house could have a lunch prepared for them in a snap. Spaghetti, tacos, fajitas, burritos, lasagna, burgers - just make a bigger meal once and you've done 95% of the work!
