Wash and drain the spinach if needed, and add to the pan. 

Slice the mushrooms and add to the pan along with the peeled and finely chopped garlic. 

Peel ginger and grate into the pan. Add finely chopped chili the pan (remove seeds first for less heat, keep for extra heat)

Put the pan on the hob on a medium/high heat and move the spinach around regularly to cook evenly and prevent sticking. 

Cook for around 7-10 minutes until all of the spinach is wilted. 

Remove from heat and serve.
