Savory Stuffed Mushrooms

I discovered this recipe in a diabetic cookbook.  Katie was very skeptical when she read the ingredients list and didn't see cheese or butter.  So, I humored her and added a bit of feta cheese to the top.  However, she was pleasantly surprised, as was I!  These really are delicious and very healthy!  Enjoy!

1 Tbsp Olive Oil
1 cup finely chopped onions
1/2 cup finely chopped mushrooms
2 garlic cloves, minced
kosher salt and freshly ground black pepper
1 cup well-drained and finely chopped fresh spinach
1/2 cup chopped ground walnuts
16 large button mushrooms, stemmed and left whole
Feta cheese, crumbled

1. Preheat the oven to 350 deg Fahrenheit.
2. Heat the oil in a large skillet and cook the onions, chopped mushrooms, and garlic, stirring, for about 10 minutes  Season to taste with salt and pepper.  Stir in the spinach and cook for about 5 minutes.  Remove from the heat and stir in the walnuts.  Finely chop the mixture again.
3. Stuff each button mushroom with the filling and put on a greased baking sheet.  Top each mushroom with Feta cheese pieces.  Bake for about 10 minutes.  Serve warm.
