Creating Korean BBQ Steak Rice Bowls is straightforward if you follow these simple steps:

1. Marinate the Steak: In a bowl, mix soy sauce, brown sugar, sesame oil, minced garlic, grated ginger, rice vinegar, and black pepper. Place the flank steak in the marinade, ensuring it is well-coated. Cover and refrigerate for at least 15 minutes, or up to 2 hours for more flavor.
2. Cook the Rice: While the steak is marinating, cook your rice according to package instructions. Once done, fluff it with a fork and set aside.
3. Prepare the Vegetables: While the rice cooks, wash and slice the bell peppers, shred the carrots, and cut the broccoli into florets.
4. Cook the Steak: Heat a grill pan or skillet over medium-high heat. Remove the steak from the marinade (discard the marinade) and cook for about 4-5 minutes on each side, or until it reaches your desired doneness. Let it rest for a few minutes before slicing.
5. Sauté the Vegetables: In the same pan, add the sliced bell peppers, shredded carrots, and broccoli. Sauté for about 5-7 minutes until they are tender-crisp.
6. Assemble the Bowls: In serving bowls, start with a base of cooked rice. Top with sliced steak, sautéed vegetables, and a sprinkle of chopped green onions and sesame seeds.
7. Serve and Enjoy: Your Korean BBQ Steak Rice Bowls are ready to enjoy! Serve them warm and share the love with family and friends.
