Sam's Spring Fattoush Salad

Thin-skinned Persian, Armenian, or Japanese cucumbers, which have few seeds, a snappy texture, and a distinct sweetness, are what make the salad special. In a pinch, European hothouse cucumbers can be substituted, but avoid the typical grocery-store cukes, which are too seedy and wet for this recipe. Part of what makes this salad so great is the dynamic textures; the cracker-like baked lavash croutons and the crunchy cucumbers and radishes contrast with the creamy feta and soft herbs. I dress this with an especially tart vinaigrette made from equal parts lemon juice and olive oil and serve it right away, before it gets soggy.
