Espinacas con Garbanzos [Spinach and Chickpeas]

Place a large saucepan over medium heat and add half the olive oil. When it is hot, add the spinach with a pinch of salt (in batches, if necessary) and stir well. Remove when the leaves are just tender, drain in a colander and set aside. Heat 2 more tablespoons olive oil in a frying pan over medium heat. Fry the bread for about 5 minutes or until golden brown all over, then the remaining tablespoon of oil and the garlic, cumin and pepper. Cook for 1 minute more or until the garlic is nutty brown. Transfer to a food processor, blender or mortar and pestle along with the vinegar, and mash to a paste. Return the mixture to the pan and add the drained chickpeas and tomato sauce. Stir until the chickpeas have absorbed the flavors and are hot. Season with salt and pepper. If the consistency is a little thick, add some water. Add the spinach and cook until it is hot. Check for seasoning and serve with paprika on top, or on fried bread toasts (as the Spanish do).
