0 a thick omelette (= a flat, round food made by frying eggs that have been mixed together), with potato and sometimes onion or other vegetables in it:
Tortilla española is also known as Spanish omelette and is not at all the same as Mexican tortillas.
The Spanish omelette, if made with care, should be a quivering, tender slice of tiny yellow potatoes and sweet onions.
One of my favourite tapas is a big Spanish omelette cut into cubes served cold with toothpicks.
