Start by chopping your onion, garlic, and bell pepper. Having these ready before you start cooking can make the process smoother and ensure everything gets cooked evenly.
In a large saucepan, heat the olive oil over medium heat. Add the ground beef, breaking it up with a wooden spoon as it cooks.
Stir in the chopped onion, garlic, and bell pepper. Cook until the vegetables are softened, about 5 minutes.
Add the diced tomatoes and beef broth to the pan. Stir in the salt, black pepper, thyme, and paprika.
Lower the heat and let it simmer for about 20 minutes. Serve over cooked rice.
Notes
Store leftovers in an airtight container in the refrigerator for up to three days, or freeze for up to three months.
