Mushroom egg rolls are a delicious vegetarian option that highlights the earthy flavors of mushrooms. The food processor can be used to finely chop a variety of mushrooms, such as shiitake, cremini, or button mushrooms. These mushrooms can then be sautéed with garlic, ginger, and soy sauce for added flavor. The filling is then rolled up in egg roll wrappers and deep-fried until crispy. Mushroom egg rolls are a great appetizer or snack option for mushroom lovers.
