In a large pot, heat a splash of oil over medium heat. Add the ground meat and cook for about 5–7 minutes, breaking it apart with a wooden spoon. Stir occasionally until it’s browned and no longer pink. Drain any excess fat.
Add the diced onion, bell peppers, and minced garlic to the pot. Sauté for about 4–5 minutes until the onions are translucent and the peppers are tender.
Stir in the diced tomatoes, broth, and cooked rice. Sprinkle in the Italian seasoning, salt, and pepper to taste. Mix everything well.
Raise the heat to high and bring the soup to a rolling boil, which should take about 5 minutes.
Once boiling, reduce heat to low and cover the pot. Allow the soup to simmer for about 30 minutes, stirring occasionally.
Remove the lid and taste the soup. Adjust the seasoning if needed and add more broth if the soup is too thick.
