Making beef stir fry with rice is straightforward if you follow these simple steps:

1. Prepare the Rice: Rinse the jasmine rice under cold water. In a medium saucepan, combine rice and water. Bring to a boil, then cover and reduce to a simmer for about 15 minutes, or until rice is fluffy and water is absorbed.

2. Marinate the Beef: In a bowl, toss the sliced beef with soy sauce and cornstarch. Let it sit for about 10 minutes to tenderize.

3. Heat the Oil: In a large skillet or wok, heat vegetable oil over medium-high heat.

4. Cook the Beef: Add the marinated beef to the pan in a single layer. Let it sear for about 2-3 minutes until browned, then stir-fry until cooked through, about 3 more minutes. Remove from pan and set aside.

5. Stir-Fry Vegetables: In the same skillet, add the sliced onion, bell peppers, and broccoli. Stir-fry for about 5 minutes until the vegetables are tender-crisp.

6. Add Garlic and Ginger: Add the minced garlic and grated ginger to the vegetables, stirring for about 1 minute until fragrant.

7. Combine Beef and Vegetables: Return the cooked beef to the skillet with the vegetables and mix well, cooking for an additional 2 minutes to heat through.

8. Season: Taste and season with additional soy sauce, salt, and pepper if desired.

9. Serve: Fluff the cooked jasmine rice and serve topped with the beef and vegetable stir fry.

10. Garnish: Optional: Sprinkle with chopped green onions and sesame seeds for added flavor and a beautiful presentation.
