Cook rice according to package instructions.
In a large skillet, heat olive oil over medium heat.
Add onion and garlic, sauté until fragrant and the onion becomes translucent, about 2 to 3 minutes.
Add ground beef, cook until browned, breaking it up and cooking until no pink remains and edges get a little caramelized.
Stir in bell pepper and mixed vegetables, cook for another 5 minutes until vegetables are heated through and peppers are crisp-tender.
Add soy sauce, Worcestershire, salt, and pepper to taste. Stir so the sauce glosses the beef and vegetables for even seasoning.
Serve the beef mixture over rice, and add optional toppings if desired, the bowl should be saucy with contrasting textures from tender rice and crisp-tender veg.
