Mix butter, sugar, and vanilla thoroughly.  Blend in
     flour and salt.  Mix in nuts, using hands if necessary
     to thoroughly mix dough.

     Shape dough into 1" balls and place 1  1/2" apart on 
     cookie sheets.

     Bake in preheated 400* oven for 10-12 minutes, until 
     just beginning to brown.

     While still warm, roll in powdered sugar.

     Cool on wire racks.

     When cool, roll again in powdered sugar.

     Makes 5-6 dozen cookies.

    Note:  You can make this recipe vegan by using
     soy margarine instead of butter ... but it won't
     taste as good.
