salt and pepper, extra virgin olive oil
Sautée the salad either on the stovetop or in the oven; when it will appear slightly withered, place the butterflied anchovies over the salad, to cover it completely.

At this point, place a final layer of salad on top of the anchovies, season with oil, salt, and pepper, and bake in a hot oven at 365°F until golden brown.
