Top the eggs with mayonnaise, scatter a few chopped chives over and your "œufs-mayo" are ready.
Remarks
If you don't have time to make the carrot salad, a simple green salad will go well, too.
In the photos, the mayonnaise is piped with a forcing bag. This looks more attractive, but is not essential. You can just use a small spoon to put the mayonnaise on top of the eggs.
