Preheat the oven to 400F.
Scrub the mushrooms well first, then just snap out the stems.
They'll come out easily, no need to use a knife.
Lightly fry the mushrooms, cap-side down, in hot oil for 2-3 minutes.
Mix bacon, mushroom stems, and cream cheese.
Spoon about 1/2 to 1 tablespoon of mixture into each mushroom cap.
Bake in the oven for about 20 minutes or until the mushrooms are nicely browned.
Serve immediately.
Once cooked, stuffed mushrooms do not hold up well for long periods.
