Spicy Beef Bulgogi Wraps

1.In a medium bowl, combine soy sauce, mustard, ground cumin, minced garlic, sugar, gochujang (or chili flakes), and sesame oil. Whisk well to create the marinade.

2.Add the thinly sliced beef and sliced onions to the marinade. Toss thoroughly to coat all pieces. Cover and refrigerate for at least 30 minutes to allow flavors to meld.

3.Heat vegetable oil in a large skillet or wok over medium-high heat until shimmering.

4.Add the marinated beef and onions to the skillet in a single layer. Cook, stirring frequently, for about 4-5 minutes or until the beef is cooked through and slightly caramelized. Avoid overcrowding the pan to ensure proper searing.

5.Stir in the finely diced tomato during the last minute of cooking to soften slightly without losing shape. Adjust seasoning with salt if needed.

6.Remove from heat and transfer the beef mixture to a serving bowl.

7.To assemble, place a spoonful of the spicy beef bulgogi onto a fresh lettuce leaf. Sprinkle with toasted sesame seeds if using.

8.Serve immediately as wraps, encouraging diners to fold the lettuce around the filling and enjoy as a Korean-inspired appetizer.
