You could boil the fine onion before you add to the egg and milk if you do not like crunchy onion.
My 2 year old loved this for his lunch today! I used a spring onion instead of regular onion though. Very yummy! :-) - 21 Apr 2015
I left out the onion as I was just looking for a recipe for regular eggy bread. The milk and egg mixture was just the right amount so nothing wasted. I mis-read the instructions and didn't cook the bread for long enough - but 40-50 seconds would have been about right. I was out of ketchup, so I served it with salsa which went really well. - 30 Dec 2012
