Raw Stuffed Mushrooms

This recipe is from "Alive In 5" by Angella Elliot. Here goes...
1 pound of fresh mushrooms
1 bell pepper, diced
1 cup pitted raw olives
1 tbsp extra-virgin olive oil
2 tbsp minced fresh basil
1 1/2 tbsp freshly squeezed lemon juice
1/8 teaspoon freshly ground black pepper

Clean the mushrooms.Carefully remove the stems and set the caps aside. Place stems in food processor along with the bell pepper, olives, oil, basil, lemon juice, and black pepper, and pulse to chop. Divide the mixture equally among the mushroom caps and serve. Think I might have some stuffed mushrooms for lunch.
