In a large skillet, heat oil over medium. Add onion; cook, stirring occasionally, until beginning to brown, 5 to 8 minutes. Add garlic, coriander, and cumin; cook, stirring, until fragrant, 1 to 2 minutes.
Add tomatoes, chickpeas, zucchini, and 1/2 cup water; season with salt and pepper.
Cover skillet; simmer mixture over medium-high heat, stirring, until zucchini is tender, 10 to 12 minutes. Season with salt and pepper, as desired, and serve.
For even more flavor, sprinkle the saute with chopped cilantro, and garnish with lime wedges just before serving.
