• 1 teaspoon finely grated fresh lemon zest
• 1/4 teaspoon sugar
• 1/4 teaspoon salt
• 1/4 teaspoon black pepper
• 1/3 cup plus 1 tablespoon olive oil
• 6 cups thinly sliced Napa cabbage (1/2 lb; from 1 head)
• 4 1/2 cups loosely packed fresh flat-leaf parsley leaves (3 large bunches)
• 2 cups thinly sliced radicchio (1/4 lb)

Instructions

1. Whisk together lemon juice, zest, sugar, salt, and pepper until sugar is dissolved, then add oil in a slow stream, whisking until emulsified.
