Sausage Stuffed Mushrooms

Sausage Stuffed Mushrooms (a variation of Rachel Ray's Recipe, thank you!)
Preheat oven to 500 degrees

1 tablespoon extra-virgin olive oil
24 large gourmet stuffing mushroom caps, stems removed and reserved brushed with damp towel
Salt
Cracked Black Pepper

Mushroom Stuffing Ingredients:

1 1/2 teaspoons virgin olive oil
3/4 pound sweet or mild bulk Italian sausage
4 cloves garlic, chopped
20 stems mushrooms, finely chopped
1 rib of celery and green, leafy top from the heart of the stalk, chopped
1/2 small onion, chopped
1 (10-ounce) box chopped frozen spinach, defrosted and squeezed dry
3 slices white bread, toasted and buttered, chopped into small dice
1/3 cup grated Parmesan
Couple dashes of cayenne pepper
salt
cracked black pepper

Directions:

Heat a large skillet over medium high heat. Add oil and mushroom caps and season caps with salt and pepper. Saute caps 5 to 7 minutes, until they are lightly browned and tender on edges. Turn caps up and let juices drain away from caps. Transfer caps to a small nonstick baking sheet. Wipe out skillet and return to heat. Add a touch of oil and sausage to the hot skillet. Brown and crumble sausage for 3 minutes, after having dashed the cayenne in. In a food processor pulse and chop the garlic, add mushroom stems and pulse to chop the mushroom stems. Add celery, onion and red bell pepper to the mushrooms and pulse to chop. Remove mixture from the processor and saute veggies and mushrooms over medium high heat another 3 to 5 minutes. Add dry, defrosted spinach and stir into stuffing. Add chopped bread and cheese to the pan and toss stuffing until bread is moist and stuffing is combined, 2 or 3 minutes. Fill caps with stuffing using a small scoop or large spoon. Place caps in hot oven and reduce heat to 450 degrees F. Bake 6 to 8 minutes to crisp edges of stuffing and set stuffing in mushrooms. Transfer stuffed mushrooms to a serving plate.
