I can't imagine that you're going to enjoy this meal, so why not treat it like a giant steak salad. Cut up the steak, potato, salad and mix it in a bowl. Cut up the roll, and use it like croutons. Add some moisture - like salad dressing or vinegar.
Then you can just shovel it down fast before your stomach knows what's there. Eating fast seems to be the key to these contests - once you start eating you don't dare pause for cutting or moving plates.
Prepare, then shovel! :-)
Good idea, I have been thinking about doing that, although some of our doctors and scientists here seem to have different opinions. But hey, isn't FR great? Where else could a guy get such good advice about such an important issue?
