Prepare your ingredients by chopping garlic, ginger, and green onions while cooking the rice.
In a large skillet, heat a splash of oil over medium heat. Add minced garlic and grated ginger; sauté for about 30 seconds until fragrant.
Increase heat to medium-high and add ground beef. Cook until browned and no longer pink, breaking it apart (about 5 minutes).
Stir in soy sauce and brown sugar; simmer for about 3 minutes to meld flavors.
Add bell peppers and carrots; sauté for another 3-4 minutes until tender yet crisp.
Serve over warm rice, topped with sliced green onions.
