1. In a medium-sized pot, heat one tablespoon olive oil on medium heat. Add zucchini with salt and pepper to taste, stirring occasionally. Sauté for 4 to 5 minutes, or until the vegetable softens but retains slight crispness. Remove zucchini from pot and set aside. 

2. In the same pot, heat two tablespoons olive oil on medium heat. Add onions and garlic, and sauté for 4 to 5 minutes, or until onions are softened and translucent. 

3. Add the millet to the pot, and toast for 2 to 3 minutes, stirring occasionally. 

4. Add the vegetable broth, water, and curry powder. Bring to a boil, then simmer on low, covered, for 15 to 20 minutes, checking occasionally. 

5. When the millet is softened, turn off the heat and allow it to sit for 5 minutes. Fluff with fork, before adding zucchini, chickpeas, and raisins (if using). Season to taste with salt and pepper, and return to heat for 1 to 2 minutes to warm if necessary.
