How to Make It
Heat a large skillet over medium-high heat. Add the oil and then stir in the onions. Cook for about 2 minutes or until the onions are soft.
Add the garlic, corn and mushrooms and stir occasionally until the mushrooms are lightly browned and tender, 3 to 5 minutes.
Stir in the Worcestershire sauce and apple cider vinegar. Cook until heated through and season with salt and pepper.
Toss with chopped parsley and serve warm.
