I would have gone in another direction. The introduction of manchego cheese as a main ingredient would seem to call for less-flamboyant accompaniments, perhaps a vegetarian celebration, but there it is, anchovies, and you certainly do taste anchovies.
This part of the menu, or at least my recent quantum-physics-based orders, seem to have landed me in a deep well of green bell peppers, as in an inexpertly tossed salad, but in this case I welcome my Capsicum annuum overlords. That crispy green bite helps put the anchovies in their place.
This isn't a great montadito, but it's better than it might sound.
