Being American, I've never heard of fairy bread which is evidently an Australian treat. I'm not sure I'd want to eat white bread with margarine and sprinkles but it sure looks adorable!
The first time I ever saw eggs in a basket was in a black and white slapstick comedy from the 40s. I wish I could remember what the movie was. I was watching late at night probably about 12 years ago now and was so inspired by this snack they ate onscreen that I had to make it immediately. It has since become a standby snack that I will eat at any time of day. Nowadays I add Sriracha and maybe some quick sauteed greens and call it lunch. Excuse me, I have to go turn on the stove now.
