For the mushrooms, use any you like that are fresh; Button, Straw, and Shiitake would be excellent in this. Oyster, King Oyster, Shimeji, White Crab or a mixed pack would be good choices as well.
Melt the butter in a large non stick pan on medium heat, when hot, add the onion. Sauté until just softened.
Add the garlic and mix in, cook until fragrant.
Add the wine and increase heat to medium high, cook for about 3 minutes or until the wine is nearly evaporated.
Add the mushrooms and soy sauce, sauté until the mushrooms are tender and cooked through, about 5 minutes or as needed.
Remove from heat, stir in the parsley.
Serve as a side dish with any main dish, enjoy.
