You’d think quiche would be a summer picnic staple. In practice, the beloved cheese pies are too darn messy. Cutting one into slices while you’re sitting in the wild or at the beach can be tricky. And if you figure, “Aha! I’ll slice it up ahead of time,” you discover there’s no easy way to transport the individual wedges. Finally, however you transport your quiche to the picnic, it’s gotta be served with a knife and fork. No way. Picnics are all about finger food.
