Put the broth and tomatoes in a microwaveable bowl. Microwave on high for 5 minutes, or until steaming.
Heat the oil in a large pot over medium-high heat. Add the onion, celery, and carrot. Cook, stirring frequently, for 5 minutes, or until tender. Add the Italian seasonings and pepper flakes. Cook for 1 minute, or until fragrant.
Add the broth mixture to the pot. Add the beans, peas, escarole, and pasta. Season to taste with salt and pepper. Cover and bring to a simmer, then reduce heat to medium-low. Continue to simmer, partially covered and stirring occasionally, for 15 minutes, or until the vegetables are soft and the pasta is tender.
