Thinly slice the mushrooms lengthwise.
In a large frying pan over medium heat, warm olive oil and slightly cook the garlic until soft and fragrant (be careful and do not let the garlic brown). Add the sliced mushrooms and season with salt and pepper. Cook just until tender, approximately 20 minutes, stirring occasionally.
Add parsley towards the end of the cooking time and stir in. Remove from heat and serve warm.
Makes 4 servings.
* A portobello mushroom is a very large cremini, and a cremini is a brown or cream-colored version of the white button mushroom. The flavor of the portobelo is the same as that of the common supermarket mushroom, except it is more distinct because it is older and more developed.
