Heat the oil in a deep 20cm non-stick frying pan. Fry the potatoes, onion and garlic for 10 mins until tender. Stir in the paprika and fry for 1 min more.
Beat the dried or fresh herbs into the eggs with seasoning, then pour into the pan. Stir a couple of times as the egg starts to set on the bottom of the pan, then leave alone to cook slowly over a very low heat for 10 mins until set, except for the very top.
Carefully slide the tortilla onto a plate. Slide back into the pan, with the uncooked top now on the bottom, and cook for 1-2 mins more. Garnish with parsley, if using, wrap in foil and serve warm or chilled.
