Pour sherry into a saucepan, season with salt and pepper to taste. Add herbs, bread crumbs, remove from the stove, cover, and set aside to soften bread crumbs.

Heat the olive oil in a large skillet, place the fish and fry until golden brown on all sides.
Transfer the fried fish to a paper towel-lined plate and place in the oven to keep the fish warm.
Fry the remaining fish, transfer to the same plate. Serve the fried salsa and salsa.
