A food processor makes crushing quick; for example, graham crackers for a pie crust. For another easy way, place them in a large zip-top plastic bag and remove as much air as possible. Seal the bag and place it on the countertop. Pound the bag using a rolling pin or heavy can. This can also be a fun opportunity to get your kids involved with cooking!
