4 tablespoons of olive oil
1 1/2 pounds fresh broccoli
1 large onion, chopped
1 zucchini, chopped
Salt and freshly ground black pepper
3 tablespoons all-purpose flour
4 cups low-sodium vegetable broth
Homemade Croutons, recipe follows
Add 4 tablespoons of olive oil in heavy medium pot over medium-high heat. Add broccoli, onion, zucchini, salt and pepper and saute until onion is translucent, about 6 minutes. Add the flour and cook for 1 minute, until the flour reaches a blonde color. Add stock and bring to boil.
Simmer uncovered until broccoli is tender, about 15 minutes. With an immersion blender, puree the soup. Add salt and pepper, to taste, and then replace the lid back on the pot.
