It’s That Simple is our series about recipes so easy, you can make them with your eyes closed. Also known as le Parisien, a jambon-beurre sandwich is as simple as it gets. This is an audacious vegetarian version—which is to say, entirely untraditional and a little unhinged. It’s pantry-friendly and picnic-ready, as welcome for a chic desk lunch as it is for a day in the sun.
