Heat the oil or butter in a large cast iron skillet over medium heat. Sauté the onion for 3 minutes, add the ginger, cook another 3 minutes until onions are golden brown. Add the garlic, cook another minute then add the tomatoes, coconut milk, spices and lemon juice. Bring to a simmer and cook about 10 minutes, stirring well. Taste the sauce and season with salt and pepper to your liking.

At this point you can puree the sauce in a food processor or blender…or not. Just depends if you prefer a silky smooth sauce. If you pureed it, return the sauce to the skillet. Add in the chickpeas and heat over medium heat until simmering.

Top with fresh cilantro & serve immediately with rice of naan.
