In a large pot of boiling salted water, cook pasta according to package instructions; drain well and set aside.
Heat 1 tablespoon olive oil in a large stockpot or Dutch oven over medium heat. Add Italian sausage to the skillet and cook until browned, about 3-5 minutes, making sure to crumble the sausage as it cooks; drain excess fat and set aside.
Add remaining 1 tablespoon oil to the stockpot. Stir in garlic, onion, carrots and celery. Cook, stirring occasionally, until tender, about 3-4 minutes.
Whisk in vegetable broth [See Note 1], tomato sauce, diced tomatoes, Italian Seasoning Spice blend, and Italian sausage; season with salt and pepper, to taste. Bring to a boil; reduce heat to a simmer. Cover the pot with a tight-fitting lid and cook until vegetables are tender - about 10-15 minutes.
Stir in the beans until just heated through - about 3 minutes.
If serving the full soup with no anticipated leftovers, add the pasta to the soup and stir to combine. Otherwise, I add mine to the bowls at serving. Pasta continues to soak up the soup broth at it sits in the refrigerator.
