Hi,
Here is my take on all this... Egg beaters are known as an egg "substitute". Pretty much still an egg but processed and modified for persons watching cholesterol and fat. Here is the lowdown on egg beaters...
99% real eggs
No fat
No cholesterol
Less than half the calories of shell eggs
All the protein of shell eggs
12 essential vitamins and Minerals
Pasteurized for safety
No preservatives
Available refrigerated or frozen
Multiple sizes for any occasion, including convenient resealable pour spout packaging
As for the western egg... where I live a western sandwich or omlette would be scrambled egg with peppers, ham and onion. If you add cheese then it would be called a Denver. A chef who worked for us set me strait on this... but I am sure it might vary by region!
