Last meal on Earth? Without hesitation: feta sesame pizza with a honey drizzle.
I think good meal isn't all about the food. Some of the best meals I've ever had were eating PBJ's on top of an Adirondack mountain or a bowl of microwaved mac and cheese in the dorms. Food is about half of the equation, the other half would be the people to share it with. Since it seems I have complete control this meal in my hypothetical situation, I would put everybody I've ever known there. And the president. Why settle?
