Rinse the white rice under cold water until the water runs clear.
In a small saucepan, combine the rinsed rice and 1 cup of water. Bring to a boil over medium-high heat.
Once boiling, reduce heat to low, cover, and simmer for 15 minutes or until the water is absorbed and rice is tender.
While the rice cooks, heat 1 tablespoon of olive oil in a medium non-stick skillet over medium heat.
Add the sliced onion, bell pepper, carrot, and broccoli florets to the skillet. Sauté for 5-7 minutes until the vegetables are tender-crisp.
Push the vegetables to one side of the skillet. Add the ground beef to the empty side.
Season the ground beef with salt, black pepper, garlic powder, and onion powder.
Cook the ground beef, breaking it apart with a spatula, until browned and cooked through, about 6-8 minutes.
Mix the cooked beef and vegetables together in the skillet.
Add 1 teaspoon soy sauce and 1/2 teaspoon dried Italian seasoning to the beef and vegetable mixture. Stir well and cook for an additional 1-2 minutes.
Fluff the cooked rice with a fork and transfer to a serving plate.
Top the rice with the ground beef and vegetable mixture.
Serve immediately.
