How to cook
Wash the vegetables well, cut them into large pieces, and put them in a large pot filled with water on the stove to boil. When it boils, add salt to taste.
Once soft enough, remove from the heat. Wait for it to cool down a bit and with the help of a blender, mash the vegetables, if you wish, you can take away some of the water to make the soup thicker.
Add black pepper to taste and fresh parsley.
Before serving, you can season with flavoured olive oil or, in winter, with fried bacon finely chopped.
