Preheat oven to 325 degrees F. Grease a 9 x 13-inch pan, or any other 3-quart pan, with I Can't Believe It's Not Butter!®. Set aside.
Cut each roll into 8 pieces (cut into more pieces if you'd like smaller bread pieces). Place the bread into a large bowl, set aside.
In a large skillet, melt I Can't Believe It's Not Butter!® over medium heat. Add the celery and onion and cook until slightly browned on the edges and tender, about 5-6 minutes.
Pour the celery & onions mixture over the bread. Add the dried thyme, pepper, parsley, macadamia nuts, cranberries, and broth. Stir the mixture until combined, and the broth is absorbed.
Cover with foil and bake for 35 minutes. Remove the foil and bake another 10-15 minutes, or until the bread is toasted. Serve.
