Me: So i guess you don't want to go out. Shall we eat around here? Or shall i go out and get you something.
Her: You should go get me something.
Me: Pizza Hut? Burger King? Del Taco?
Her: Nothing sounds good right now.
Me: Pizza? Burger? Taco?
Me: Pizza-Burger-Taco? ... Hey wait, that sounds like something that could actually work!
So you make a really small pizza, using some set of toppings that includes hamburger meat, and when it's done cooking you fold it in half. (But don't seal the edges! We want a Pizza-Burger-Taco, not a Pizza-Burger-Calzone!) Personally i'd want to use the same toppings as the incredibly awesome Bacon Cheeseburger pizza from BJ's. Cheese, hamburger, bacon, pickles, tomatoes, and "special sauce."
Of course for the deluxe version (just in case we're not overdoing it enough already) french fries could be folded into the Burger-Pizza-Taco after it was done cooking. (This would also help prop up the "burger" part of the triad, since depending on the toppings chosen that's the weakest part.)
Unfortunately it would probably never work as a fast food idea. The pizza cooking part would just take too much time. It could be done for sit down restaurants though, or as a part of an order from a pizza place, kind of a variant on the "personal pizza" thing.
So is this...
What toppings would you want in _your_ Burger-Pizza-Taco?
