All this time I thought frittata had to have little bits of potato in

but no! It's just a quiche without the pastry.

You can put anything in or take anything out (except the eggs).

Why did I not know this? All these years I could have been making frittata but the spuds stopped me.

You're thinking of the spanish version maybe...tortilla? Nearly always has potato in it. The italian frittata, not so much. We usually have spinach in frittata.
