2 ounces fresh arugula (about 1/3 of a 5-ounce package or about 3 cups)
Instructions
In a large soup pot over medium heat, melt butter or heat oil. Add celery and sauté until soft, about 5 minutes. Add garlic and sauté for about 1 minute.
Add water, bay leaf, salt and pepper, and peas. Simmer over low heat for 15 minutes. Turn off heat and remove bay leaf. Add the greens and allow to wilt for 30 seconds to 1 minute, stirring.
Puree with an immersion blender or in batches in a blender, adding water if you want a thinner consistency. Process longer for completely smooth soup, less for a more rustic soup with flecks of darker green.
Ladle into bowls and garnish with a little additional pepper, if desired.
