In a large saucepan, sauté the olive oil, fennel, celery, and leeks for about 10 minutes. Add the garlic and zucchini and saute another 5 minutes, or until everything’s soft.

In a bowl or large measuring cup, mix the bouillon into the water to make a veggie broth, then add to the veggie mix. The veggies should be completely covered in broth. Simmer gently for 10-15 minutes, stirring occasionally.

Remove from heat and pour in a large ceramic bowl to cool a little (or whatever works). Purée everything with an immersion blender, regular blender, or food processor.

Once the veggies are puréed, add the milk and blend, just briefly. Place back on the stove and heat again, stirring frequently, and be careful not to boil.

Garnish with a spring of fennel and a drizzle of olive oil.
