- 2 tablespoons reduced-sodium soy sauce
- 2 tablespoons balsamic vinegar
- 2 teaspoons brown sugar
- 2 teaspoons toasted sesame oil
- 1 clove garlic, minced
- 1 teaspoon chopped fresh ginger
- 2 teaspoons black peppercorns, crushed
- 1 (12 ounce) sirloin steak, trimmed
- 1/8 teaspoon salt
- 16 scallions, white part only
- 1 red bell pepper, halved lengthwise and seeded
- 1 cup curly endive (frisee)
- 1 cup chopped radicchio
- Preheat an outdoor grill for high heat and lightly oil the grate.
- Blend soy sauce, vinegar, brown sugar, sesame oil, garlic, and ginger together in a blender or food processor until dressing is smooth.
- Press peppercorns into both sides of steak and season with salt.
- Place steak, scallions, and red bell pepper on the preheated grill and cook for 4 minutes. Flip and cook until vegetables are charred and steak is cooked to desired doneness, about 4 minutes more. Let steak rest on a work surface for 5 minutes before thinly slicing along the grain. Cut scallions into 1-inch pieces and bell pepper lengthwise into strips.
- Toss curly endive and radicchio with the dressing in a bowl; transfer to a platter and top with steak and vegetables.
