Spiced Stuffed Mushroom Caps

I am a sucker for stuffed mushroom caps and they would be a weekly menu item at my house if they were a little healthier.  I usually make them when I have some mushrooms in the fridge that need to be used up.
I wanted to stray from my regular recipe so I looked online and found this one.  It was a little on the spicy side for my liking but that would be simple enough to fix but cutting the amount of cayenne pepper in them.  I hope you like them.

Spiced Stuffed Mushroom Caps

12 whole fresh mushrooms

1 tbsp vegetable oil

1 tbsp minced garlic

1 (8 oz) package of cream cheese

1/4 cup grated parmesan cheese

1/4 tsp ground black pepper

1/4 tsp ground cayenne pepper

1.

Bring a large pot of lightly salted water to a boil. Add ziti pasta, and cook until al dente, about 8 minutes; drain.

2.

In a large skillet, brown onion and ground beef over medium heat. Add spaghetti sauce, and simmer 15 minutes.

3.

Preheat the oven to 350 degrees F (175 degrees C). Butter a 9x13 inch baking dish. Layer as follows: 1/2 of the ziti, Provolone cheese, sour cream, 1/2 sauce mixture, remaining ziti, mozzarella cheese and remaining sauce mixture. Top with grated Parmesan cheese.

Bake for 30 minutes in the preheated oven, or until cheeses are melted.
