Preheat oven to 350F Combine flour, soda and salt. Set aisde. In a large bowl, cream sugars and butter very well. Add eggs and vanilla. Beat well. Gradually add flour mixture and mix well. Stir in chocolate chips. Stir in the 2 cups of nuts. Mix well.
Drop by rounded teaspoonsfuls onto ungreased cookie sheet and bake for 7-10 minutes. Cookies should look slightly Underdone when you take them out. Let them rest a minute before removing them from the sheet onto a rack to cool. Note: you may want to add a bit of flour for the 2nd batch if the first batch you baked is a bit too thin or if they seem greasy. (This depends on the weather and the flour you use too.) Enjoy!
