Cook ground beef over medium high heat, breaking it up into small crumbles with a wooden spatula as its cooks.
Once beef is cooked through drain off any excess fat.
Add rice, beef broth, soy sauce, oyster sauce, Worcestershire sauce, and rice vinegar.
Stir in sriracha sauce if using.
Stir to combine.
Add garlic powder and pepper. Stir to combine.
Increase heat and bring mixture to a boil.
Once broth is simmering, cover the pan and reduce heat to low. Simmer for 15 minutes.
Stir and add shredded carrots to the pan.
Cover and cook on low heat for another 10-15 minutes or until rice is soft and cooked through, stirring occasionally.
Once rice is soft and has absorbed all the liquid in the pan stir in the thawed peas.
Stir to combine and cook until heated through, about 1-2 minutes.
To serve, garnish with sliced green onions if desired.
