Ingredients

1/2 cup hoisin sauce

4 teaspoons sambal oelek, plus more for serving

5 tablespoons distilled white vinegar

1 red bell pepper, halved, seeded, and cut into 1/4-inch strips (1 1/2 cups)

1 small head bok choy, stems thinly sliced (1 cup), leaves reserved

Kosher salt and freshly ground pepper

1 pound ground pork

8 teaspoons mayonnaise

4 split-top hot-dog buns, such as King’s Hawaiian

1/2 cup lightly packed fresh herbs, such as mint, cilantro, or basil

Preparation

Stir together hoisin, sambal oelek, and 1 tablespoon vinegar. In another bowl, stir together bell pepper, bok-choy stems, and remaining 1/4 cup vinegar. Season with salt and pepper.

Place pork in a medium nonstick skillet over medium-high heat. Season with salt and cook, breaking up with the back of a spoon, until cooked and beginning to brown, 5 to 6 minutes (there will be some liquid in skillet). Add 1/4 cup hoisin mixture; cook until sauce is reduced and evenly coats meat, about 30 seconds.

Spread mayonnaise on buns. Serve pork in buns with bok-choy leaves, slaw, and herbs, with remaining hoisin mixture and sambal oelek alongside.
