Spanish Tortilla

Although a tortilla can be served for breakfast, it is quite often served as a Spanish Tapa or small appetizer with a glass of wine.  It is equally good served hot or at room temperature. 
Most recipes that I have seen for Tortillas call for cooking the omelette on top of the stove.  I find that it turns out better if you bake it in a cake pan  or a cast iron pan in the oven.

 (This recipe makes two Tortillas)

At least 4  large baking potatoes or 5 or 6 smaller ones
1 small onion
12 eggs
olive oil

Heat oven to 350°

Peel and cut potatoes into 1/8 to 1/4  inch slices.

Heat one or two frying pans and saute the potato slices in olive
slowly, until almost tender. Add salt and pepper.

Cut onion in half and slice thinly. Add onion to the potato mixture
and continue to saute until the onions and the potatoes are tender.  I
like the onions and potatoes to start to turn a bit golden.

Add a couple of teaspoons of olive oil or butter to two cake pans. 
Place in oven to heat.

Beat up eggs and season with salt and pepper.

Gently toss the potato mixture into eggs. Pour mixture into the two
heated cake pans.

Bake for approximately 15 minutes or until eggs are set and the
omelette is golden and puffy.

For breakfast cut into wedges and  serve   Can be served with a salsa
as well.

As an appetizer, cut into small squares and serve with a nice Spanish
Red Rioja.
