Most delicious vegetarian-friendly stuffing

My sister-in-law is vegetarian. Even though my Thanksgiving dinner has always been vegetarian-friendly, I have tried to come up with dishes that she can eat while also satisfying the rest of us carnivores. This year, I think I have come up with the ultimate stuffing recipe that EVERYONE loved. The guys were shocked when I said it was completely vegetarian!

1 large bag stuffing cubes with seasoning packet
1 small onion, chopped
2 large stalks celery, chopped
1 C chopped crimini mushrooms
2 T. butter
1 C cooked wild rice
1/2 C dried cranberries
1/2 C chopped pecans
1/2 large apple, diced (I peeled the apple because Brian doesn't like the peel, but you don't have to)
2 cans cream of mushroom soup
1 1/2 C vegetable broth
fresh ground black pepper to taste

Saute onion, celery, and mushrooms in butter until tender. In a LARGE mixing bowl, combine stuffing cubes, sauteed vegetables, wild rice, cranberries, pecans, and apple. In in a smaller mixing bowl, whisk together mushroom soup, vegetable broth, stuffing seasoning packet, and pepper. Combine soup mixture with stuffing; mix thoroughly and let stand for about an hour. Scoop stuffing into a large greased baking dish. Bake at 375° for 45 minutes.
