Okay, this is great!

How about if you're filling the omelette up?

I like to put onions and peppers inside of mine, so I usually let it cook longer before I flip it closed because it typically falls apart if I do it sooner. However, that makes the omelette dryer and it tastes better a little moist. What would you suggest? I've heard flour makes it thicker which may help prevent that but I also feel that can alter the taste.

Thanks in advance!
