Crickets and a Gecko

One of the fun things about sharing a house with a lizard, is that you have an excuse to harbor crickets. Now, Obviously the lizard loves scarfing the chirping little buggers down, but there is a part of me that eyes the cage and thinks, "wow! we could have a fun St. John the Baptist feast!"

Does anyone have any particular words of wisdom on raising and preparing crickets for human consumption?

I await your advice.
