breakfast is a horrible idea after waffles
time limit idea cant be enforced, there are many ways around it, and I know if I was given a time limit for an online competition i would cheat in a heartbeat just because I could
money limit doesnt work either, because you could go out and buy a whole bunch of food at the grocery store a day before hand, and then go out the following day and spend 10 dollars, yet use all the extra stuff at your house you just bought to add to the throwdown
fajita's/mexican would be a good idea
i still like my idea of a raw ingredient, because there are an unbelieveable amount of raw/uncooked veggies, fruits, meats, poultry, fish that you can do
