Cook your meat/beans, if using. For example, cook a couple links of turkey sausage in the same saucepan you're going to use for the soup, then remove and set aside while you cook the soup. Or, soak and cook beans. You can also use canned, drained, & rinsed beans. In a 4qt saucepan, cook celery, carrot, and garlic over medium heat in olive oil until soft, around 5 minutes. Add tomato paste and herbs and stir until fully incorporated. Add stock/water and tomatoes and bring to a boil. Simmer for 20 minutes, add green beans or peas, then simmer for another 5 minutes. Add pasta, beans, or meat and simmer for another 10. Salt & pepper to taste. Serve.
