pretty sure my colon would advise against that...
i guess you could. bread will freeze dry, but kind of difficult to hydrate it back to a decent consistency. the meat would freeze dry ok i guess, but condiments and such would not do well. french fries would be too greasy to freeze dry.
mcdonalds has so many perservatives that there is no need to freeze any of it...people report leaving a burger in the back seat of a car and finding it months later with no mold or visible damage one would expect from normal food
