One of my favorite recipes on Food 52 is the Pan Bagnat tuna sandwich. Might need a kid with a pretty sophisticated palate, but if you make it the night before, it will be perfect at lunchtime.

I just made a pasta salad that's been quite good.
Boil noodle of choice. Strain, let cool.
Roast some cherry tomatoes in olive oil with thyme, salt and pepper. Let cool.

It's really yummy and packs up nicely.
I often bring this to work with me along with some fresh fruit.
