Preheat the oven to 200ºC/gas mark 6. Heat a heavy-bottomed pan over a medium heat on the hob.
Season the steaks with salt and pepper, using your fingers to rub seasoning and olive oil into both sides of each steak. Add the steaks to the preheated pan and cook for 1-2 minutes on each side before sliding the pan into the preheated oven. Cook the steaks for a further 2-3 minutes for medium to medium-well done. Remove the pan from the oven and let the steaks rest for 2 minutes before slicing them into thin strips.
While the steaks rest, fry the eggs. Set a small non-stick frying pan over a medium heat and add the vegetable oil. Break in 1 egg. Season with a little salt and fry until the white is set. Remove to a warm plate and repeat with the remaining eggs.
If you can multi-task, heat the tortillas, either by holding them directly over a gas flame with metal tongs, or in a cast-iron frying pan set over a high heat. You want them to be puffed and a little blistered.
Place an egg on top of each tortilla and spoon the sliced steak on top of the egg. Top with ketchup and serve immediately.
