Grub's up! Which of these foods can NASA astronauts eat in space?

Astronauts have quite a menu available to them, from seafood to beef to brownies and peanut butter. But they do have some restrictions on their diet: bread, soda, alcohol, and salt and pepper aren't allowed for various reasons, for example. Astronauts are allowed salt and pepper in liquid form, but the salt and pepper granules are too messy for zero gravity.
