Cut zucchini into 1-inch cubes, and set aside. Heat 1 tablespoon olive oil over medium heat in large saucepan. Add onions and garlic, and cook until onions are soft and translucent. Add zucchini, and stir in 1 tablespoon olive oil. Cook 3-5 minutes, stirring frequently. Pour in water, and bring to a boil. Reduce heat, and simmer 15 minutes.
Remove zucchini with a slotted spoon, and place in food processor. Process until mixture is smooth (you may have to do in two batches). Return to saucepan. Place chickpeas in food processor with 1/2 cup of the soup, and process until texture reaches desired consistency.
Add chickpea mixture to saucepan. Stir in basil and salt. Simmer another 15 minutes. Serve with toasted sunflower and/or pumpkin seeds.
