Creating Spicy Korean-Style Beef Lettuce Cups is a breeze when you follow these clear steps:

1. Prepare the Lettuce: Rinse the lettuce leaves thoroughly and pat them dry. Set them aside on a serving platter.
2. Cook the Beef: In a large skillet over medium heat, add the ground beef. Cook it until browned, breaking it apart with a spatula as it cooks.
3. Add Aromatics: Once the beef is browned, add the garlic and ginger to the skillet. Stir for about 1-2 minutes until fragrant.
4. Mix the Sauce: In a separate bowl, combine soy sauce, gochujang, sesame oil, rice vinegar, and brown sugar. Mix well to incorporate.
5. Combine Ingredients: Pour the sauce mixture over the cooked beef in the skillet. Stir well to ensure the beef is evenly coated.
6. Finish Cooking: Continue cooking for another 3-5 minutes, allowing the flavors to meld and the sauce to thicken slightly.
7. Add Veggies: Mix in the shredded carrots and chopped cucumber, stirring until combined and heated through.
8. Serve: Spoon the spicy beef mixture into lettuce cups. Garnish with sliced green onions, sesame seeds, and cilantro if desired.

These simple steps will lead you to create a delicious dish that is as enjoyable to make as it is to eat!
