Preheat oven to 400 degrees F.
In a large heavy-bottomed pot, cook onion in butter and oil over medium heat until translucent about 10 minutes. Add the carrot and celery and cook another 5 minutes.
While vegetables are cooking, place lima beans in boiling water and cook until very soft about 10 minutes. Drain lima beans and add to the pot with the sliced apple. Pour in the chicken broth. Lower heat and simmer an additional 5 minutes. Then puree with a hand blender. Season with salt and pepper, to taste.
For the Parmesan Bacon Crisp: Line a cookie sheet with aluminum foil and spray with cooking spray. Make 4 to 5 lines with the Parmesan, about 1-inch wide and 4-inches long. Sprinkle with bacon. Bake for about 7 to 10 minutes or until golden and crisp. Remove from oven and let cool. Peel crisp from foil and serve with soup.
Cook's Note: For additional flavor, add an additional 1/2 cup of Parmesan and 1/4 cup bacon to the soup before pureeing. Also a dollop of sour cream adds a creamy finish to this healthy soup.
