"For you." Cheers. A general toast. The more formal version, or if more than one person is involved, is 'Yásass." 'Yamass' means 'for us." These cab also be prefixed by 'stin', so 'stin yasou', 'stin yassas' or 'stin yamass' are all friendly toasts.
"Stuffed aubergines." Aubergines (US: eggplants), often stuffed with minced (US: ground) beef or veal, cheese and onions or rice with chopped peppers and other vegetables or fish.
