Olivia calls this "Shrek Soup" because it's green.
5-6 small zucchini or 3 or 4 bigger ones.
1 white onion
fresh rosemary (1 sprig)
Chop up the onion and zucchini. Sautee on medium heat in olive oil and salt, until onions are transparent. Add a sprig of fresh rosemary (I added it whole and fished it out before I puree the soup) Bring it all to a boil and let it cook on medium heat for about 20 minutes. Let it cool a bit and blend with a hand blender.
Garnish with fresh rosemary.
Serves 4-5 people
