Portabellas are the king of mushrooms and are the 'steak' of the veggie world. Grill with melted cheese and peppers on the BBQ, or saut them with some balsamic vinegar and parmesan cheese.
Portabellas are the older brother of crimini mushrooms... meaning they are just the oversized, grown up version. These mushrooms are a good source of vitamin D and B vitamins, making it a great immune boosting treat.
