Step 1: Cook the Rice

1. If you haven’t already prepared the rice, cook it according to the package instructions. Fluff with a fork and keep warm.
2. For added flavor, cook the rice in chicken or vegetable broth instead of water.

Step 2: Prepare the Beef

1. Thinly slice the beef against the grain into bite-sized strips. Pat it dry with paper towels to remove excess moisture, which helps the beef sear properly.
2. Season the beef with a pinch of salt, black pepper, and crushed red pepper flakes (if using).

Step 3: Make the Stir-Fry Sauce

1. In a small bowl, whisk together the soy sauce, oyster sauce, hoisin sauce, sesame oil, rice vinegar, honey (if using), cornstarch, and water. Set the sauce aside.

Step 4: Sear the Beef

1. Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat.
2. Add the beef strips in a single layer, working in batches if necessary to avoid overcrowding the pan. Sear the beef for 1-2 minutes per side, or until browned but not fully cooked.
3. Remove the beef from the skillet and set it aside on a plate.

Step 5: Stir-Fry the Vegetables

1. In the same skillet, heat the remaining 1 tablespoon of vegetable oil over medium-high heat.
2. Add the sliced onion, red bell pepper, and green bell pepper. Stir-fry for 3-4 minutes, or until the vegetables are slightly tender but still crisp.
3. Stir in the minced garlic and grated ginger (if using), and cook for an additional 30 seconds until fragrant.

Step 6: Combine Beef, Vegetables, and Sauce

1. Return the seared beef to the skillet with the vegetables.
2. Pour the prepared stir-fry sauce over the beef and vegetables, stirring to coat everything evenly.
3. Let the mixture simmer for 1-2 minutes, or until the sauce thickens slightly and the beef is fully cooked.

Step 7: Assemble the Rice Bowls

1. Divide the cooked rice among four serving bowls.
2. Top each bowl with a generous portion of the beef and pepper stir-fry.
3. Garnish with sesame seeds and sliced green onions for a finishing touch.

Step 8: Serve and Enjoy

1. Serve the Beef and Pepper Rice Bowls hot, with extra soy sauce or chili oil on the side for added flavor.
