If you decide to smoke the mushrooms, drizzle with a little olive oil and put in heat proof pan. Start your smoker and set at 250° and let the mushrooms smoke for 20-30 minutes or until they are tender and have reduced in size. Cut mushrooms in half. (If you do not have a smoker, set 2 chunks of hardwood over charcoal and set the mushrooms over indirect heat so they don't burn and let grill until they are under, may be less time since the grilling temperature will be different.)
For the pasta: cook in boiling salted water until it is al dente. Mix the sauce/mushrooms with the pasta and sprinkle with some fresh parsley and additional rosemary. Add parmesan cheese to your liking.
