Stuffed Mushrooms

Mushrooms are practically made to be stuffed.

SIMPLY:
Remove stem and filling, so you have a cup! I like using medium-sized mushrooms, Portabello are a little too big for my taste.
Fill, with a mixture of cheese, seasoning, whatever.
Bake!

Rosemary, Goat Cheese, and Red Pepper Pesto stuffed mushrooms. 

Leftover Tomato Sauce and Parmesan [use leftover spaghetti, lasagna, whatever sauce]

Reverse Garlic-Bread Mushrooms: Stuff mushrooms with garlic, parmesan, top with breadcrumbs and parsley! a bit of lemon juice before baking.
