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 11x13" 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.
