Crimini or (sometimes called baby bella mushrooms) are medium-size brown mushrooms, typically slightly larger than button mushrooms and with a meatier texture and flavour, but not quite as robust (or large) as their grown-up counterpart, the portobello.
Besides being low in calories, creminis provide several nutrients your body needs. They deliver fiber, which aids in digestion, and riboflavin, which is important for energy production, as well as selenium which may reduce the risk of cardiovascular disease.
