Raw broccoli is made for slaw. It's sweet and crunchy—and can be dressed hours in advance.

2/3 cup buttermilk

1/3 cup mayonnaise

3 tablespoons fresh lemon juice

Kosher salt, freshly ground pepper

1 small bunch broccoli (about 12 ounces)

1/2 medium Napa cabbage, thinly sliced (about 6 cups)

2 scallions, thinly sliced

8 ounces sugar snap peas, thinly sliced

4 tablespoons chopped fresh chives, divided

Preparation Combine buttermilk, mayonnaise, and lemon juice in a small bowl; season with salt and pepper and whisk to combine. Set buttermilk dressing aside. Using a vegetable peeler, peel broccoli stalk if skin is thick. Halve broccoli lengthwise, then thinly slice crosswise, starting at crown. Toss broccoli, cabbage, scallions, sugar snap peas, 2 tablespoons chives, and reserved buttermilk dressing in a large bowl; season with salt and pepper. Serve slaw topped with remaining 2 tablespoons chives. DO AHEAD: Slaw can be made 6 hours ahead. Cover and chill.
