Method

1. In a medium saucepan, parboil the potatoes in boiling salted water for 5 minutes or until just tender. Drain the potatoes and set aside.
2. Place the steaks between two sheets of cling film and using a rolling pin, roll out the steaks to flatten (cut off the rind of fat optional). Season the steaks on both sides with salt & black pepper.
3. In a medium sauté pan heat a little olive oil, then sauté the steaks for 1 minute on both sides to color, then remove from the pan and set aside to rest.
4. In the same pan on high heat add a little more oil if necessary. Add the shallots (season with salt & black pepper) sweat for a minute then add mushrooms, garlic and butter, and stir.
