Preheat oven to 200°C. Rub steak with small amount of oil and season with salt and pepper.
Heat a small stove-top-proof baking dish on the stove over a very high heat, then add meat. Sear for a couple of minutes on both sides until brown and set aside on a plate.
Cut potatoes into thin wedges or chips (so they cook quicker), place in baking dish and toss with remaining oil and rosemary. Bake for 20 minutes, tossing once or twice.
Add steak and tomatoes to the pan, pushing chips to the sides and cook for a further 10 minutes.
Remove steak to rest for a few minutes, return baking dish with chips and tomatoes to the oven and turn oven off to keep warm.
Thinly slice steak (it should be medium-rare) and serve with rocket and tomato, squeezing two tomatoes over for a dressing. Scatter over pine nuts and serve with chips and mustard.
