In a large pot, heat olive oil over medium heat. Add chopped onion, diced carrot, and diced celery. Sauté until the vegetables are softened, about 5 minutes.

Brown the Beef

Add the ground beef to the pot. Cook until browned, breaking it apart with a spoon, about 5-7 minutes. Drain excess fat if necessary.

Add Garlic and Tomatoes

Stir in the minced garlic and diced tomatoes. Cook for another 2-3 minutes until the tomatoes soften.

Add Broth and Beans

Pour in the chicken or vegetable broth and add the drained white and red beans. Stir to combine.

Season the Soup

Add the Italian seasoning, salt, and black pepper. Bring the soup to a boil, then reduce heat and let it simmer for about 15 minutes.

Cook the Pasta

Stir in the tubetti pasta and cook according to package instructions, usually about 8-10 minutes, until al dente.

Serve

Taste the soup and adjust seasoning if necessary. Ladle into bowls and garnish with chopped fresh parsley before serving.
