Creating Beef Bulgogi Bowls is a simple process if you follow these steps:

1. Prepare the Marinade: In a bowl, mix soy sauce, brown sugar, sesame oil, minced garlic, grated ginger, gochujang, and black pepper.
2. Marinate the Beef: Add the sliced beef to the marinade, ensuring it is well-coated. Cover and refrigerate for at least 30 minutes.
3. Cook the Rice: While the beef marinates, prepare the rice according to package instructions.
4. Sauté the Vegetables: In a skillet over medium heat, add a drizzle of oil. Sauté the mixed vegetables until tender, about 5-7 minutes. Remove from heat and set aside.
5. Cook the Beef: In the same skillet, increase the heat to high. Add the marinated beef in a single layer and cook for 3-5 minutes, stirring occasionally until browned and cooked through.
6. Assemble the Bowls: In bowls, add a scoop of cooked rice, topped with a generous portion of the cooked beef and sautéed vegetables.
7. Garnish: Sprinkle sesame seeds and chopped green onions over the top. Add fresh cilantro or parsley if desired.
8. Serve: Enjoy your Beef Bulgogi Bowls while warm!
