Preparing your own chickpeas is both frugal and incredibly easy! A packet of dried chickpeas costs very little, and I always prepare the whole packet. It can seem like a lot but they are easy to freeze down in portions and add to stews etc.
In a large bowl,  soak the peas for at least 12 hours. Use three times the amount of water as chickpeas, they will expand a lot! In very hot weather, you may need to rinse and refresh the water that they are soaking in.  Rinse the chickpeas and add to a pot with a few teaspoons of salt. Cover with at least 4 inches of water, they will expand further as they cook, and some water will evaporate, so it is a good idea to start with a little too much water rather than adding more later. Bring to a boil, reduce the heat and simmer for 45 minutes – 1 hour until soft. Drain well and allow to cool before freezing.
