Preparation

• Position a rack 6 inches from the broiler and heat the broiler on high. Line a large heavy-duty rimmed baking sheet or broiler pan with foil and put the steak on it.
• Whisk the gochujang, sesame oil, soy sauce, and garlic in a small bowl. Rub 3 Tbs. of the mixture all over the steak and let marinate at room temperature for 10 minutes. Whisk the vinegar into the remaining gochujang mixture and set aside in a small serving bowl.
• Arrange the scallions, carrots, and lettuce on a large serving platter in individual mounds. Place the kimchi in a serving bowl.
• Broil the steak, flipping once, until medium rare (125°F), 3 to 4 minutes per side. Let rest for 5 minutes, then slice thinly against the grain. Season to taste with salt and mound on the serving platter. Bring all the components to the table for everyone to assemble their wraps as they like.
