I came across this and thought immediately of JJR and his KFC-hankering at SuperBowl time. Many suggested he learn how to make compliant versions of the faster-food dishes he and others like.
Well: Here are recipes for all sorts of items from all sorts of chain-joints.

I noticed, also @JJR, they have Panera's recipes.

Haven't used it (yet) myself, but it looks worthy of investigation, anyway.
Thousands of ideas
