- 1 1/2 lb zucchini (about 3 large)
- 1 1/4 teaspoons salt
- 1/2 lb arugula, stems discarded and leaves cut into 1/2-inch-wide strips (6 cups)
- 1 oz Parmigiano-Reggiano, coarsely grated (on large holes of a box grater; 1/2 cup)

- 1/4 teaspoon black pepper
- Special equipment: an adjustable-blade slicer
- Cut zucchini crosswise into paper-thin slices with slicer.
- Toss zucchini slices with 1 teaspoon salt in a large colander set over a bowl and let drain 20 minutes.
- Rinse zucchini slices well, then drain, pressing gently on slices to extract any excess liquid. Pat zucchini slices dry with a kitchen towel.
