"Pancreas." Sweetbreads, thymus glands, rather than testicles. They are usually prepared in the same way as kidneys or are served with a vinaigrette.
"Little shoes." Slices of aubergine (US: eggplant) with a stuffing of mince (US: ground meat), tomatoes and béchamel sauce.
Please. To be slightly more formal it is correct to say 'se parakaló' or, if representing a group of people 'se parakaloúme'.
