In a large mixing bowl, beat shortening and butter with an electric mixer on medium to high speed about 30 seconds or until softened. Add about half of flour to shortening mixture. Add brown sugar, sugar, eggs, vanilla and baking soda. Beat until thoroughly combined. Beat in remaining flour. Stir in vanilla chunks and nuts. Drop dough by rounded teaspoons 2 inches apart onto ungreased cookie sheets. Bake in a 375 degree oven for 8 to 10 minutes or until edges are lightly browned. Remove cookies; cool on wire racks. Makes about 60.
