Cook the rice according to package instructions.

In a large skillet, heat vegetable oil over medium heat. Add the ground turkey and cook until browned (about 5 minutes).

Stir in chopped bell peppers and grated carrots; sauté for about 3 minutes until tender.

In a small bowl, mix teriyaki sauce, soy sauce, and brown sugar. Pour over the turkey mixture in the skillet.

Reduce heat and let simmer for another 5 minutes.

Serve the turkey mixture over bowls of rice, drizzling extra teriyaki sauce on top if desired.
