1 c  Olive oil, or a mixture of o
Vegetable oil
4    Large potatoes, peeled and c
Slices
1    Large onion, thinly sliced
Coarse salt
4    Large eggs

Heat the oil in an 8 or 9- inch skillet and add the portato slices one at a
time so they dont stick togeather. Alternate layers of potato and onion
slices and salt the layers lightly. Cook slowly over medium heat (the
potatoes will really “boil” in the oil rather than fry), lifting and
turning the potatoes occasionally, until they are tender but not brown. The
potatoes should remain separated, not in a “cake”. Drain the potatoes in a
colander, reserving about 3 tablespoons of the oil.(the onion and potato
give the oil a wonderful flavor, so save the rest for some other use.) Wipe
out the skillet, scraping off any stuck particles. (If this is difficult to
do, wash the skillet. It will be used again to set the omelet and must be
completely clean to avoid sticking.) Meanwhile, in a large bowl beat the
eggs with a fork until they are slightly foamy. Salt to taste. Add the
potatoes to the egg, pressing down with a pancake turner so that they are
completely covered by the egg. Let the mixture sit for 15 minutes. Heat two
tablespoons of the reserved oil in the skillet until it reaches the smoking
point. (It must be very hot or the eggs will stick.) Add the potato and egg
mixture, spreading it out rapidly in the skillet with the aid of a pancake
turner. Lower the heat to medium high and shake the pan often to prevent
sticking. When the eggs begin to brown underneath, invert a plate of the
same size over the skillet and flip the omelet onto the plate. Add about 1
talbespoon more oil to the pan, then slide the omelet back into the skillet
to brown on the other side. Lower the heat to medium and flip the omelet
two ot three more times (this helps to give the omelet a good shape while
it continues to cook), cooking briefly on each side. It should be juicy
within. Transfer to a platter and cool, then cut in thin wedges or into 1 –
1 1/2- inch squares that can be picked up with toothpicks [May be prepared
ahead]. Fat grams per serving: Approx. Cook Time:
