Beat until well combined. Add the egg mixture. Cook until set, pushing sides to center occasionally to allow wet portions to flow to bottom of pan, about 4 minutes. Cut into quarter wedges and carefully turn each wedge to enable top side to get done, about another 2 minutes. This omelet is equally good served hot or room temperature.
Leftovers make an excellent sandwich.
Amounts of ingredients called for can easily be adjusted to individual tastes. Diced ham or other meats can also be added.
