Ingredients

4 heads baby bok choy (about 1 pound)

1/4 cup white-wine vinegar

2 tablespoons tomato-based chili sauce

2 teaspoons light-brown sugar

2 tablespoons vegetable oil

Coarse salt and ground pepper

Preparation

Heat grill to low. Trim large leaves from baby bok choy; halve heads lengthwise. Rinse well under cold water to remove grit.

In a large bowl, whisk together white-wine vinegar, tomato-based chili sauce, light-brown sugar, and vegetable oil; season with coarse salt and ground pepper. Add bok choy; toss to coat. Remove from bowl, reserving sauce.

Place bok choy, cut sides down, on grill; cover, and cook until tender, about 10 minutes. Serve bok choy drizzled with reserved sauce.
