Season the steaks with a little salt and black pepper.
Heat the pan or barbecue. Cook the steaks for 3-6 minutes on each side, depending on how you like them cooked. Allow to rest for a few minutes before serving.
While the steaks are cooking, mix together the salsa ingredients.
Serve with the steaks and some baked potatoes.
For a quick steak on the go, slice the steak thinly and serve in a pitta bread along with a spoonful of salsa and some dressed salad leaves.
