How to Make It
Clean mushrooms by wiping caps and stems with a moist paper towel to remove any dirt. Cut mushrooms into large chunks. (Do not remove tender stems.) Set mushrooms aside.
Pour sunflower oil into a skillet large enough to fit all the mushrooms. Heat oil over high until shimmering. Add spring onions, and cook, stirring occasionally, until lightly browned and slightly tender, 3 to 4 minutes. Add mushrooms; cook, stirring occasionally, until they begin to soften and release their liquid, 4 to 5 minutes. Stir in garlic, chile, sage, mint, and tarragon. Sprinkle with salt and pepper, and cook, stirring occasionally, until mushrooms are lightly browned, 2 to 3 minutes.
Spoon mushroom mixture onto a serving plate, and sprinkle lightly with crushed red pepper before serving.
