Melt the ghee in the skillet over medium heat. Add the diced leeks, sauté until translucent.
Add the Garam Masala, turmeric, ground ginger, cinnamon, and pepper. Stir briefly to toast the spices.
Add the coconut milk, tomato paste and salt. Stir until all are blended well and then add the chickpeas.
Cook over medium-heat, stirring frequently until the sauce thickens (10-15 minutes).
Serve the chickpea curry with a squeeze of lime, a dollop of yogurt and garnish with plenty of cilantro.
