Preheat oven to 325 degrees.
Using an electric mixer, cream the butter and sugar on slowest speed until light and fluffy. Add the vanilla and salt. Add flour making sure not to over mix. Fold in pecans by hand. Form dough into 1 1 /2 inch diameter balls and place on baking sheet lined with parchment paper. Using the palm of your hand, flatten the dough until it is about 1 /4 inch thick. Bake 15-18 minutes, just until cookies begin to brown.
Yield: 16-20 cookies
