In a small pot, soften the zucchini, potato, shallot and garlic in the oil. Season with salt and pepper. Add the broth and bring to a boil. Cover and let simmer for about 15 minutes or until the potato is tender.
In a blender, purée the soup until smooth. Adjust the seasoning. Garnish with yogurt, drizzle with olive oil and sprinkle with fresh chives if desired.
To make this velvety soup into a meal, add a nice thick slice of toasted bread and, for more protein, when puréeing in the blender, you can add a boiled egg.
