Every single dish is delicious! Here is a list of food I gave someone on TSR once.
Șnițel (schnitzel) is my favourite food ever and although it originated from Germany/Austria, it has become a traditional dish in Romania. It is meat (most commonly chicken breast, sometimes pork thigh or turkey breast) that is beaten with a special hammer, then covered in egg and flour or egg and breadcrumbs.
Sarmale is a well-known traditional dish which is basically boiled mincemeat in lettuce leaves (there are some more ingredients like rice but I do not like sarmale do IDK what they are).
Biscuit salami (salam de biscuiți) is exactly what it sounds like: a salami-shaped sweet treat made with biscuits, chocolate, and often Turkish delight, nuts, and/or coconut.
Mămăligă is basically what Romanians used instead of bread years ago and it is still eaten nowadays; it is made by boiling hominy and salt and letting it cool for a bit in order for it to take a soft solid shape.
Supă de găluște (literally 'dumplings soup', which is more or less accurate) is a traditional soup. The 'dumplings' are made with eggs, salt, a bit of oil, and semolina, which are mixed until the dumplings are neither liquid not solid. These dumplings are formed with the spoon you are mixing them with and thrown into the soup one by one. The soup base itself only has salt, pepper, oil, parsley, and light-colored vegetables (like carrots or parsnip), and maybe sour cream if you feel like it. It is also delicious.
Ciorbă de fasole (a kind of beans soup, though it is not a soup, it is a ciorbă, which is a variation of soup) is delicious and is made by boiling beans, tomatoes, and whatever other vegetables you feel like putting in with salt. It is important to note that the end result will be mainly liquid, the only solids being the beans and the vegetables.
Ciorbă de perișoare (which is apparently some kind of soup with meatballs, though they are not exactly meatballs) is also a ciorbă, but with slightly different ingredients (tomatoes are not a must here) and those meatball-like things.
Lapte de pasăre (literally 'bird milk' - misleading name) is a sweet food made by boiling milk, adding in some really soft and non-liquid/non-solid dumplings made of sugar and egg whites, and finally adding vanilla pudding. It is delicious and the dumplings end up more or less solid.
We also have musaca, which we took from the Turks; it is made by putting a bed of boiled potatoes on a baking tray, adding mincemeat with egg, another sliced boiled potatoes layer, and ketchup over the top (but not over the entire top, just a bit), then baking it. It is delicious, of course.
We also have budincă de cartofi (literally 'potato pudding' - misleading name again), which is made by boiling cut potatoes, mixing them with egg and cheese, putting the mix on a baking tray, adding a layer of egg on top, and baking it. I love this dish too since it is sooo good.
There is also cozonac. This is a traditional type of cake made for Christmas, Easter, etc. There are many variations but all of them use a base made of flour, egg, oil, sugar, salt, and milk, moulded in a special baking tray. The filling can be Turkish delight, nuts, cocoa, fruits, etc.
Mici (literally 'littles'
are basically tiny cylinders of mincemeat about as thick as two fingers and as long as your little figer which are grilled (or, very rarely, fried). Often served with mustard and bread, sometimes with ketchup. They are delicious as well.
