Pour in the broth, and add the allspice, bay leaf, salt, and black pepper. Let it simmer gently for about 5 minutes. Then, stir in the sliced celery, baby tomatoes, a handful of frozen peas, and the pasta. Continue cooking until all the vegetables are tender, which should take about 5-8 minutes. To finish, sprinkle in the chopped parsley. Serve and enjoy your meal!
