Cook rice according to package instructions and set aside.

In a skillet over medium heat, add ground beef and cook until browned, about 5-7 minutes.

Drain excess fat if necessary.

Add diced onion, bell pepper, garlic, and ginger to the skillet. Cook until vegetables are tender, about 5 minutes.

Stir in soy sauce and sesame oil, mixing well.

In serving bowls, layer cooked rice and top with the beef mixture.

Garnish with sliced green onions and optional toppings like avocado and sriracha.
