Lol, well, haven't seen the movie in a long while so I don't remember exact things, but yes, while some things may be exaggerated a little for the comedy element, it can be like that, typically for rural families - definitely not your average city family though.
Some popular foods - I have chosen the most popular ones, but anyone interested can see more in the wikipedia article here:
[You must be registered and logged in to see this link.]Greek salad: known as 'village' salad here, a salad typically including tomatoes, cucumbers, red onions, feta cheese, occasionally peppers and/or olives, dressed with olive oil.
Patatosalata: potato salad (which is what the word means) with olive oil, finely sliced onions, mayonnaise, lemon juice or vinegar.
Saganaki: fried yellow cheese, usually graviera cheese.
Skordalia: (from skordo/σκόρδο = garlic) thick garlic and potato puree, usually accompanies deep fried fish/cod. Veeeeeeery strong taste and smell (honestly the smell makes me almost faint lol).
Spanakopita: spinach, feta (sometimes in combination with ricotta cheese), onions or scallions, egg and seasoning wrapped in phyllo pastry in a form of a pie.
Taramosalata: fish roe mixed with boiled potatoes or moistened breadcrumbs, olive oil and lemon juice. Very popular on Clean Monday (our first day of the Lent). Well, popular to other people, I don't like it at all lol.
Lagana bread, also traditionally had on Clean Monday
Tzatziki: yogurt with cucumber and garlic puree, used as a dip. Another one with a strong/aroma and taste, you can either love it or hate it, pretty much.
Tirokafteri, cheese spread (a little spicy).
Fakes, a lentil soup, usually served with vinegar and olive oil.
Fasolada, a soup made of beans, tomatoes, carrot, celery and olive oil usually served with a variety of salty side dishes.
Gemista, baked stuffed vegetables. Usually tomatoes or peppers, hollowed out and baked with a rice-and-herb filling or minced meat.
Spanakorizo, spinach and rice stew cooked in lemon and olive-oil sauce.
Giouvetsi: lamb or veal baked in a clay pot with kritharaki (orzo) and tomatoes.
Pastitsio: an oven-baked layer dish: Béchamel sauce top, then pasta in the middle and ground meat cooked with tomato sauce at the bottom. A favorite of mine ^^
Moussaka: an oven-baked layer dish: ground meat and eggplant casserole, topped with a savory custard which is then browned in the oven.
Souvlaki: grilled small pieces of meat (usually pork but also chicken or lamb) served on the skewer for eating out of hand, or served as a sandwich wrapped in pita bread together with tomatoes, onions, tzatziki and tomato sauce; a popular fast food.
Loukoumades, similar to small crusty donuts, are essentially fried balls of dough drenched in honey and sprinkled with cinnamon.
Melomakarona, Christmas cookies soaked with a syrup of diluted honey and then sprinkled with crushed walnuts.
Vasilopita, Saint Basil's cake or King's cake, a popular desert for New Year's Day (usually had right after midnight). Traditionally baked with a coin inside, and whoever gets the coin in their slice are considered blessed with good luck for the whole year.
