Clean your mushrooms. Some people say not to rinse them but to brush them. But to be honest if they are very dirty, I will want to rinse them properly. Just pat them dry afterwards.
Cut mushrooms into desired size. You can leave them whole if they are very small.
Heat up a skillet with the olive oil and add in your mushrooms.
Keep over high to medium heat and season your mushrooms with salt and black pepper.
Sautee and stir occasionally. Reduce mushrooms or cook until cooked through.
Serve up hot as a side dish with other main courses and side dishes.
