Here we go again, yet another obscure day to celebrate.
Apparently a day for those people who enjoy their omlette to be aware that there are many other things you can add to an omelette than just eggs. So make your groceries last longer therefore creating less waste in the long term. According to the organisers (?). This can be a day to have fun with omlette.
So I wish you and your omlette a very happy day!!!
