Summer vegetable soup

Dietitian's tip:

Take advantage of the wealth of summer vegetables and herbs to make this flavorful soup. Despite the long list ingredients, the soup comes together quickly.

Ingredients

1. 1 tablespoon olive oil
2. 1 yellow onion, chopped (about 1 cup)
3. 3 cloves garlic, chopped
4. 4 plum (Roma) tomatoes, peeled and seeded, then diced
5. 1 tablespoon chopped fresh oregano or 1 teaspoon dried oregano
6. 1 teaspoon ground cumin
7. 4 cups no salt added vegetable stock or broth
8. 1 bay leaf
9. 1 carrot, peeled, halved lengthwise, and thinly sliced crosswise (about 1 cup)
10. 1 yellow bell pepper, seeded and diced (about 1 cup)
11. 1 zucchini, halved lengthwise and thinly sliced crosswise (about 1 cup)
12. 1 tablespoon grated lemon zest
13. 2 tablespoons chopped fresh cilantro (fresh coriander)
14. 1/4 teaspoon salt
15. 1/4 teaspoon freshly ground black pepper

Directions

In a large saucepan, heat the olive oil over medium heat. Add the onion and saute until soft and translucent, about 4 minutes. Add the garlic and saute for 30 seconds; don't let the garlic brown. Add the tomatoes, oregano and cumin and saute until the tomatoes are softened, about 4 minutes.

Add the stock and bay leaf and bring to a boil, then reduce the heat to medium low and bring to a simmer. Add the carrot and bell pepper and cook for 2 minutes. Add the zucchini and simmer until the vegetables are tender, about 3 minutes longer. Stir in the lemon zest and cilantro. Season with the salt and pepper. Discard the bay leaf.

Ladle into individual bowls or mugs and serve immediately.
