Pour broth into a pot and place over the heat. Keep on medium to high heat and bring to a slow boil.
Pour pastina pasta noodles into the cooking broth and mix. Allow to cook and make sure to stir occasionally to avoid the noodles from sticking at the bottom.
Season with salt to taste ad cook noodles soft.
To serve, pour soup with noodles into a bowl or shallow plate and garnish with a rosemary sprig and/ or parmesan. The garnish is optional
Notes
The fresh rosemary and Parmesan garnish are totally optional. These are traditionally used in northern Italian homes.
