Egyptian Breakfast Beans (Ful Medames)

Drain and rinse the beans and add them to a large pot. Cover with 4 inches of water and bring to a boil over high heat. Reduce the heat to medium, cover, and cook until the beans are tender, 1½ to 2 hours. 2. While the beans are cooking, sauté the onion in a medium skillet or saucepan over medium heat for 8 to 10 minutes, or until it is tender and starting to brown. Add the garlic, cumin, and lemon zest and juice and cook for 5 minutes longer. Set aside. 3. When the beans are fully cooked, drain all but ½ cup of the liquid from the pot and add the onion mixture to the beans. Mix well and season with salt to taste. Serve garnished with the lemon quarters.
