Wrap the potato in a damp thick kitchen paper and then wrap it with plastic wrap. Place it on a microwave-safe plate and heat in a 600W microwave for 4 minutes. Let it cool slightly, peel the skin, and cut into bite-sized pieces.

Trim the stems of the mushrooms and cut them in half.

Cut the sausages diagonally into 1cm slices.

Heat salad oil in a frying pan and add the mushrooms. Stir-fry over medium-low heat for about 3 minutes until the mushrooms soften.

Add the potato and sausages to the pan and stir-fry for 1-2 minutes.
