The after-school snack is a complex beast. We like to think of it as a precisely calibrated mini-meal: hearty enough to tamp down a raging post-school appetite, but not so filling as to ruin dinner. It should be small, but not too small, and easy to prepare or make ahead. And we also think it should be cheesy, just because, well, everything should be. That's why we're focusing on everything from snack-sized sandwiches to flaky spring rolls. With so many tasty snacks to pick from, you may want to eat them all up before your kid even gets home from school.
