- salt and pepper to taste
- 5 tablespoons olive oil or vegetable oil
- 1 cup loosely packed fresh basil leaves
- 1/2 cup chopped walnuts
- 2 garlic cloves, minced
- 1/2 teaspoon salt
- 1/3 cup grated Parmesan cheese
- 4 slices mozzarella cheese
- 1 cup sliced fresh mushrooms
- Flatten chicken to 1/4-in. thickness; sprinkle with salt and pepper. In a large skillet, cook chicken in 1 tablespoon oil for 5-10 minutes on each side or until juices run clear.
- Meanwhile, for pesto, combine the basil, nuts, garlic, salt and Parmesan cheese in a blender or food processor; cover and process until well blended.
