Heat 3 tablespoons olive oil in a large pot over medium heat. Add the
garlic, onion, carrots, celery, rosemary, red pepper flakes, and cook 2
minutes. Stir in the tomatoes and cook 2 more minutes; season with salt.
Add 3 quarts water, the vegetable base (or a bouillon cube), the bay leaves
and Parmigiano Reggiano rind. If you don’t have the cheese rind, the soup will still turn out fine!
Cover and bring to a boil, then reduce the heat to low and simmer for about 45 minutes with pot slightly covered.
Uncover the pot and raise the heat to medium. Add the chickpeas and let it simmer for about 15 minutes. If you are adding pasta to the soup, add it now with the kale. If you are not adding pasta, just add the kale and cook stirring occasionally until the leaves are tender (about 7-10 minutes)
Remove the bay leaves and the cheese rind. When serving the soup, add a drizzle of olive oil on top of each portion (and a little bit of grated Parmigiano Reggiano, if you like). Salt and pepper to taste.
for the crostini-
Slice the loaf in half and then slice it crosswise. Drizzle the bread with olive oil. Sprinkle on the salt, chopped garlic and parsley. Bake on 350 F until lightly browned (about 10 mins…depends how toasted you’d like your crostini).
Top each bowl of soup with a a slice of the crostini and enjoy!
