Creating the Beef and Pepper Rice Bowl is simple if you follow these steps:

1. Prepare the Rice: Rinse the rice under cold water. In a medium saucepan, combine the rice and water or broth. Bring to a boil, then cover and reduce heat to low. Cook for 15-20 minutes until the rice is tender and water is absorbed. Remove from heat and let it sit covered.

2. Marinate the Beef: In a mixing bowl, combine the sliced beef, soy sauce, oyster sauce (if using), salt, and pepper. Mix well and set aside to marinate for about 10-15 minutes.

3. Cook the Beef: Heat 1 tablespoon of vegetable oil in a large skillet over medium-high heat. Add the marinated beef and cook for 3-4 minutes or until browned and cooked through. Remove from the skillet and set aside.

4. Sauté the Vegetables: In the same skillet, add another tablespoon of oil. Add the sliced bell pepper and onion. Sauté for about 3-5 minutes until the vegetables are tender but still crisp. Add the minced garlic and ginger, cooking for an additional minute until fragrant.

5. Combine: Return the cooked beef to the skillet with the vegetables. Toss everything to combine and heat through for another minute or two.

6. Serve: Fluff the cooked rice with a fork. Serve the beef and pepper mixture over the rice. Garnish with chopped green onions and sesame seeds, if desired.
