Heat the olive oil in a large skillet or shallow pot over medium heat.
Add the chopped scallions and cook, stirring frequently, for 1 minute until they begin to soften and become fragrant. 2.
Add the sliced zucchini to the skillet.
Cover and cook for 2 minutes, allowing the zucchini to soften slightly. 3. Uncover and stir in the Madras curry powder, cooking for about 30 seconds until it's very aromatic. This step toasts the spice and deepens the flavor. 4.
Pour in the water or vegetable broth, then add the thawed peas and rinsed chickpeas.
Bring the mixture to a rolling boil. 5.
Stir in the quick-cooking couscous and season to your liking with salt and pepper. If you prefer a spicier curry, now is the time to add a bit more curry powder. 6. Immediately remove the skillet from the heat, cover it tightly, and let it stand for 5 minutes. The couscous will absorb all the liquid and become perfectly tender. 7. To serve, fluff the couscous with a fork to separate the grains.
Transfer to a serving bowl and sprinkle generously with fresh parsley.
