Directions:
Puree half of the chickpeas with 1 1/2 cups of broth in a blender or food processor. In a large pot, heat the olive oil over moderately low heat. Add the carrot, celery, onion, garlic and rosemary. Cook, stirring occasionally, until the vegetables start to soften, about 5 minutes.
Stir in the remaining 1 1/2 cups broth, the pureed mixture, whole chickpeas, bay leaf, red-pepper flakes, tomatoes, pasta and salt. Bring to a boil. Reduce the heat and simmer, partially covered for 10 minutes.
Add the Swiss chard to the pot. Simmer until the chard is tender and the pasta is done, 5 to 10 minutes longer. Remove the bay leaf and stir in the black pepper. If the soup thickens too much on standing, add a little more broth or water.
Serves 6.
