My Gf, Red, is a great Cook and makes just about anything in the world. The Other Night , I bought a box of Frozen DiGiorno Pizzas that you bake. She pulled one out and baked it, and when it was served , I tried to cut it with the pizza cutter....I couldnt get the thing to cut....It was like cardboard. Finally I asked her..."Did you remove the Cardboard it was on ?", she gave me a funny look and said "What Cardboard"... She had baked the cardboard into the crust. She Had never had or fixed a frozen Pizza before last nite, she had always made them from scratch , but with her in recovery , I figured it would be easier on her... She just defended herself by saying..."Im a Hick , I never fixed one of them Newfangled things before"...But Now she Knows better....LOL God , I Love her !!!
