Preheat oven to 325º. Sift flour and salt together and set aside. Cream together butter and sugars, then add egg, vanilla and flour mixture. Press into an 11×13″ pan and bake 20-25 min. While hot from the oven, top bars with chocolate chips and let them melt. Once chips are melted, spread evenly and sprinkle with almonds. Chill and then cut, as desired.
