Scallion Cream Mushrooms on Toast

You'll need:
150 grams of button mushrooms, quartered
35 grams of scallions, sliced
100 ml of light cream
1/4 of a large lemon's zest
Salt and freshly ground black pepper
A pinch of chopped parsley
A good drizzle of olive oil
2 slices of toasted bread (Use good bread if you have some.)
Directions:
Cook the mushrooms over high heat to retain their moisture. Don't stir much at first to give them color. Once their color begins to change, add the scallions and toss. Cook for around 30 seconds. Pour in the cream and turn down the heat. Immediately after pouring the cream, add your lemon zest and season with salt and pepper. Add some chopped parsley if you'd like. Give it all a quick stir and turn off your heat. Pile over toasted bread while hot.
