Vegetable soups are a healthy way to fill up in the middle of the day. This spinach soup recipe tastes good and I feel so good after I eat it. The butter might be a problem for some so you can just substitute with olive oil.

6 tablespoons (3/4 stick) butter
6 cups chopped fresh fennel bulbs
4 cups chopped leeks (white and pale green parts only)
6 cups chicken broth
2/3 cup (packed) fresh spinach leaves

Melt butter in large pot over medium heat. Add fennel and leeks. Sauté until just translucent, about 15 minutes. Add broth to cover pot. Simmer until vegetables are tender, about 20 minutes.
Puree soup in small batches in blender until smooth, adding spinach to last batch before pureeing. Return soup to same pot.Season with salt and pepper. (Can be prepared 1 dau ahead. Refrigerate until cold, then cover and keep refrigerated.)
Rewarm soup over low heat, stirring occasionally. Ladle into bowls and serve.

Makes 8 servings.
