Wash the leeks thoroughly, drain them well and chop or slice them; you should have about 2 ½ cups. |
2
|
In a large nonstick skillet, cook the leeks in the olive oil on medium heat, with a sprinkle of salt, until they are soft and tender – about 8-10 minutes. |

|
Meanwhile, scrub and dice the potatoes and put them in a large soup pot with 4 cups water and a teaspoon of sea salt. |
4
|
Simmer the potatoes, covered, for about ten minutes as you slice the asparagus and the zucchini, and wash the spinach leaves. |
5
|
Add the green vegetables to the pot, along with the cooked leeks. Simmer everything together for about fifteen more minutes. Add the mint leaves during the last few minutes. |
6
|
Remove the soup from the heat, add the vegetable broth, and allow the soup to cool slightly, then purée it until it is smooth. |
7
|
Return the soup to a clean pot, stir in a little lemon juice and a pinch of cayenne pepper, and taste. |
8
|
Correct the seasoning if needed. If the soup seems too thick, add a little more water or vegetable broth. |

|
Swirl a thread of fruity olive oil over the top of each serving, then garnish as you please with crumbled goat cheese, or croutons. |

|
For a real treat, sauté a few fresh, peeled fava beans in olive oil and garlic, and scatter them across each bowl of soup. |

|
Put the chopped garlic in the pan with the hot oil for no more than a minute before adding the favas, then toss over medium heat for five or six minutes – and they’re ready. |
