Make big time food chains (McDonalds,Arby's,Burger King, etc.) show us exacxtly how our meat is prepared

Though out many years many of your hamburgers, sausages, hot dogs have been deep frozen for weeks & slapped in a microwave. many chemicals are put in the foods to keep the food from going bad. I feel that if these food chains would publish the steps prepared preparing our food, many people would not like the results. thank you
