Mushroom steamed buns are a delicious and earthy option for a vegetarian or vegan meal. These buns are filled with a mixture of sautéed mushrooms, onions, and herbs. The dough is made from a combination of flour, yeast, sugar, and water, which is then steamed to perfection. The result is a soft and fluffy bun with a savory and aromatic filling. Mushroom steamed buns can be enjoyed on their own or served with a side of soy sauce or a dipping sauce of your choice.
