Cut the stale bread into small slices or cubes, put it in a bowl, and cover it with a damp kitchen towel so it softens a little while you prepare the other ingredients.
In a large pan, fry the diced bacon in olive oil until crisp, then remove it and set aside.
In the same pan, fry the pork, cut into similar-sized cubes, until crisp, then remove it too.
Sauté the finely chopped garlic in the oil and add it to the fried bacon.
Stir the paprika and a little water into the remaining oil, then add the bread cubes. Cook over low heat, stirring constantly, until the crumbs are moistened on all sides, then turn golden brown.
Before serving, sprinkle the fried bacon, meat and garlic over the crumbled bread.
