I'm a lover of egg white veggie omelettes. I was dining at a restaurant and was told they could not prepare an egg white omelette without cheese. The server offered no explanation other than the kitchen had told the servers it must be prepared with cheese and that they could not enter the order in their computer to hold the cheese. I went ahead and ordered the egg white omelette with mushrooms, broccoli and the cheese that she said would be necessary for the preparation. I had expected to find a bit of shredded cheese in the omelette to help hold it together but instead the cheese was mostly in the middle and somewhat saucy or soupy when I cut into the omelette. What do you think could be the reasoning for the cheese?
