3 tablespoons extra virgin olive oil
1 lb fresh shiitake mushroom, stemmed,thinly sliced (or a mix of sliced mushrooms, if you prefer)

fresh ground black pepper

Preparation

Heat olive oil in large skillet or pot over medium high heat.

NOTE: if you like broccoli more\"done\", cook a bit longer; this recipe will yield a fairly crisp, crunchy broccoli.
When broccoli is done*close* to your preference, add butter or a bit of extra oil to the pan, and add onion and thyme.
Saute for a minute or two; add mushrooms and saute until mushrooms are tender and hot.
Garnish with parmesan and more pepper.
Serve at once.
