Broccoli and Arugula Soup

INGREDIENTS 1 tablespoon olive oil
1 clove garlic, thinly sliced
1/2 yellow onion, roughly diced
1 head broccoli, cut into small florets (about 2/3 pound)
, 2 1/2 cups water
, 1/4 teaspoon each coars,e salt and freshly ground black pepper, 
3/4 cup arugula (watercress would be good, too)
, 1/2 lemon.

DIRECTIONS

1. Heat the olive oil in a medium nonstick saucepan over medium heat. Add the garlic and onion and sauté for just a minute or until fragrant.
2. Add the broccoli and cook for four minutes or until bright green.
3. Add the water, salt and pepper, bring to a boil, lower the heat and cover. Cook for eight minutes or until the broccoli is just tender.

Pour the soup into a blender and puree with the arugula until quite smooth. Be very careful when blending hot liquids; start slowly and work in batches if necessary (you don’t want the steam to blow the blender lid off). Serve the soup with a bit of fresh lemon.
