Stuck in the same old lunch program? With this delicious mixture of mushrooms and white beans on hand, you can enjoy a delicious and satisfying lunch in a few minutes. Inspired by the classic Beef Wellington flavors, oyster mushrooms are cooked in a Düssel style with rich Dijon mustard. The white beans add some cold resistance, the melted Switzerland brings an irresistible creamy taste, and the fast pickled red onions refresh all the earthy and rich flavors below.
