Have you ever cooked dried beans before? Not much different than other dried beans.
Basically soak them overnight, drain water, then add water to cover by an inch or so. You can cook them in a crockpot during the day or cook them on the stove for about 2 hours (not sure of exact time)
You can't out-exercise poor eating habits.
Don't let the chickpeas scare you because they take so long to cook. Other dried beans take much less time, so please experiment. Hey- they are SO cheap. Some people add a touch of baking soda when doing chick peas to help break them down. Anyone do that?
