Ingredients

1 tablespoon olive oil
1 clove garlic, thinly sliced
1/2 yellow onion, roughly diced
1 head broccoli, cut into small florets
2 1/2 cups water
1/4 teaspoon coarse salt
1/4 teaspoon black pepper, freshly ground
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 4 minutes or until bright green.
3. Add the water, salt, and pepper; bring to a boil; lower the heat; and cover. Cook for 8 minutes or until the broccoli is just tender.
4. 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.
