Sprinkle water over the bread cubes to dampen them, then pour over the milk.
Put 2 tablespoons of olive oil into a wok on a medium-high heat. Working quickly, add the chorizo first. Let it caramelize and, when it releases its oil, add the peppers for a minute, then the shallots, paprika, pine nuts and hazelnuts. Next add the crumbled morcilla, then the sherry. Cook to evaporate the alcohol, then squeeze out the migas (the soaked bread) a little and add to the pan, moving everything around quickly to make sure nothing burns. Season with salt and pepper.
Pour 1cm of oil into a separate pan and put on a medium heat. Crack in the eggs, 2 at a time, and fry until they are crispy at the edges – I like to spoon some of the hot oil over the yolk, so that it cooks slightly but is still runny inside. I also lift up the white around the yolk four times so that the oil can better cook it. When the eggs are golden and crispy at the edges, remove with a slotted spoon to a paper-lined plate, then cook the next 2 eggs in the same way.
Put the crispy eggs on top of the migas, drizzle over a tablespoon of olive oil and scatter over the parsley leaves. Season with salt and pepper and cut the eggs up so the yolk runs over everything.
