Packaged Oatmeal Cookies? Wherefore Art Thou?

Years ago I developed a tart crust recipe that used packaged crisp oatmeal cookies instead of graham crackers with fabulous results. I broke them into large pieces, processed in the food processor, added melted butter and voila! An easy and really flavorful pat-in crust. I’ve noticed over the last year or so that I can’t find crisp oatmeal cookies anymore in my local supermarket. I used to be able to find a Nabisco cookie that was crisp, had no icing or raisins and was perfect for my purposes….now there are none to be found of any brand! There is one thats iced and another one or two that are soft. Where the heck did the plain crispy ones go? If you know, drop me a line.
