Jammy eggs are the star in this make-ahead French classic. Add any summer vegies you like, wrap and finish with a squish to trap all the juices. It’s the perfect picnic sandwich because it needs to be pre-assembled and squished a little, so the juices from the dressing and vegies mix and mingle together and are absorbed into the crusty baguette. It is typically made with tuna, but I like to make jammy eggs the focus, and add anchovies for a little salty umami kick (they are optional, though). Use any summer vegies you like and omit the ones you don’t – you really can’t go wrong.
