Cook the rice according to the package instructions, usually around 15-20 minutes. Bring water to a boil, add rice, lower the heat, and cover to simmer until fluffy.

In a large skillet, heat over medium-high heat. Add the lean ground beef and cook for 8-10 minutes, breaking it apart until browned.

Once the beef is cooked, drain excess fat if necessary. Stir in brown sugar, hoisin sauce, soy sauce, sriracha, ginger, and garlic, mixing well.

Return the skillet to medium heat. Add chopped red bell pepper and sauté for 2-3 minutes until the peppers are tender-crisp.

Serve the beef mixture over the cooked rice, drizzling extra sauce on top. Garnish with scallions and sesame seeds.
