Funšterc (egg omelette or coalminer's sun) is Slovenian national dish also known as knapovsko sonce (coalminer's sun) or knapovska torta (coalminer's cake) or "šmorn". It is a traditional dish from Zasavje region. In the past it was especially popular among coal miners and their families due to its basic ingredient - egg. Egg belonged to non-standard dishes because of low living standard of the population. The omelette must have been thick and round, but also tender and puffy. It was yellow like the sun, which the coal miners couldn't see while working underground. They took funšterc into coal pits and ate it at break, but only at special days.
The dish is prepared by mixing white flour with water, eggs and salt. This mixture is then poured into a baking tin and baked.
