Turn oven on to low broil. You want the oven to heat up while you cook the eggs.
Pour egg mixture into pan. Cook over medium heat for 5 minutes, uncovered. Cover and turn heat down to medium-low. Cook for an additional 10 minutes, or until eggs are just set.
Sprinkle grated parmesan cheese on top. Broil on low for 1 minute or until cheese is lightly browned.
Let stand a minute or two before slicing and devouring ;-)
