Deviled eggs are always great for parties, but it's a bit time-consuming to chop or puree everything so finely. To do it all in one step, put the hard-boiled egg yolks together with all the seasonings (e.g., mustard, capers, anchovies, parsley, etc.) into a potato ricer or a meat grinder. This way, everything is done quickly in one go.
