In a large non-stick skillet over medium heat, cook the onion in the oil until translucent, about 5 minutes. Add the ginger and garlic and cook for 2 minutes. Add the spices and tomatoes. Cook for 1 minute while stirring. Add the chickpeas and water. Bring to a boil, cover and simmer for 15 minutes. With a potato masher, mash 1/3 of the chickpeas to thicken the mixture. Let cool for 5 minutes.
This stainless steel potato masher can be used directly into your non-stick cooking pots without scratching thanks to its silicone rim. Ultra-resistant, it can withstand temperatures up to 230 °C/446 °F.
