Rinse the jasmine rice under cold water until the water runs clear. Combine the rice and water in a rice cooker and cook according to the manufacturer's instructions.

In a large skillet, heat the olive oil over medium heat. Add the sliced onion and garlic, sautéing until fragrant, about 2 minutes.

Add the ground beef to the skillet, breaking it apart with a spatula. Cook until browned, about 5-7 minutes.

Stir in the sliced bell peppers and soy sauce, cooking for an additional 5 minutes until the peppers are tender.

Once the rice is cooked, fluff it with a fork and divide it among four bowls.

Top each bowl of rice with the beef and pepper mixture.

Garnish with sliced green onions and sesame seeds if desired.
