Portabello mushrooms, when fully matured, are about the size of the a traditional ground beef burger. And this makes them perfect for grilling and creating a vegetarian-type burger.
For a bit of information, the nutritional value of a Portabello (sometimes spelled Portobella) is high in vitamin B, and they are naturally low in cholesterol and fat free, along with being nearly calorie-free. Smaller Portabello mushrooms are called Crimini, indicating a younger, unopened form of this mushroom. Crimini mushrooms are very tasteful in salads, sauted to be used as a pizza topping, and to be used in sauces (see my article on How To Saute Mushrooms and How To Make Condensed Mushroom Soup).
