Eggs 'n' brains is a breakfast meal consisting of pork brains (or those of another mammal) and scrambled eggs.
[1] It is a dish of Portuguese cuisine known as omolete de mioleira[2] (English: brain omelette).
In Austria, the dish is known as Hirn mit Ei ("calf's brain with eggs")[3] and used to be very common, but has seen a sharp drop in popularity.
In the American Midwest, the names are reversed and it is called "brains and eggs".
