Gluten-Free Food,Kiwi Style

There are many ways to do this and it comes down to personal preference.  As a child we used to place the biscuits in a plastic bag and crunch them by rolling a rolling pin over top; you can place them in a food processor (but then you have to clean it!); or my personal fave is to place them in a large bowl and press down firmly with the end of a rolling pin (great while you watch t.v.!).  Do you have another way?
