- 1 large potato, skin left on
- 3 tbsp olive oil
- 2 large flat cap mushrooms, stalks removed

- ¼ beef stock cube
- large handful watercress
Steaks will differ in size and thickness, so only ever use cooking times as a guideline. If you cut into a steak and it’s not cooked enough, you can always put it back into the pan for a few more minutes.
