This is one of those funny recipes that’s a little less a recipe than four ingredients that work magic together. I like to add a bit of Meyer lemon zest underneath the layer of bittersweet chocolate. Try it this way if you’re a lemon fan. Either way, simplicity rules here. The chocolate obviously melts so don’t obsess to much on getting perfect square of chocolate–I just chopped off uneven chunks.

Preheat the oven to 350 degrees F. Lay the bread slices on a baking sheet and sprinkle lemon zest on top. Lay a chocolate square on each and sprinkle with a little olive oil and sea salt.

Bake until the chocolate looks gooey and melted but not seeping all the way through the bread, about 5 minutes. The bread should be crisp. Out of the oven, sprinkle with a little more sea salt and a drizzle of olive oil.
