There are two kinds. The tahini based sweet, made throughout the Balkans, Middle East and South Asia in different flavours, including pistachio, walnut and marbled chocolate and vanilla. It's made without any dairy or eggs, making it one of the few sweet things allowed to believers during Lent.
Greek (or semolina) halva is an oil, semolina, sugar or honey and water pudding in syrup, often including nuts, and flavoured with cinnamon and cloves– the perfect vegan dessert, and equally okay during Lent.
