- Dice all the vegetables first and set them aside.
Preheat a Dutch oven over medium heat and add olive oil.
- Add diced onions and bell peppers and cook until they start to soften. Mix in diced tomato and cook for a few more minutes.
- Move vegetables to the sides and add ground beef to the center of the pan. Break it apart, cover the pot with a lid, and cook for a few minutes. Break up the meat some more and start mixing it with veggies. Close the lid and keep cooking until the beef is mostly done. Break up clumps.
- Mix in tomato paste and pour in beef stock.
- Season with oregano, basil, garlic powder, salt, and pepper, mix well and lower the heat to low. Close the lid but leave a small crack for the heat to escape. Cook for about 20 minutes.
- Mix in rice, close the lid and cook until rice is done.
- Serve right away.
