Ingredients

1/2 cup creamy peanut butter (not natural)

1 cup unsweetened coconut milk

1 teaspoon hot chili sauce, such as Sriracha

1 tablespoon fish sauce

1 tablespoon chopped roasted salted peanuts

1 pound flank steak, cut against the grain into 1/2-inch slices (halved crosswise if long)

1 large zucchini, cut into 3/4-inch half-moons

1 large bell pepper, cut into 1 1/2-inch pieces

1 lime, quartered

Coarse salt and ground pepper

Preparation

Heat a grill to medium-high. Clean and lightly oil hot grill. Place a small flameproof pot on grill; add peanut butter, coconut milk, chili sauce, and fish sauce and whisk until smooth and heated through. Transfer sauce to a serving bowl and top with peanuts.

Alternately thread steak, zucchini, bell pepper, and lime onto four 8-inch skewers, beginning and ending with steak. Season with salt and pepper and grill, turning occasionally, until steak is browned and cooked medium and peppers are crisp-tender, 7 to 9 minutes. Serve with peanut sauce.
