I didn't notice until I was beginning to cook that the recipe paired it with mini ham sandwiches. Luckily, I had some bread on hand, and just used that to make half-sandwiches of grilled ham and provolone. Went perfectly with it, and helped to round out the meal.
While the soup was delicious, and I'd make it again, I did find it a bit bland and had to add a fair amount of salt to my bowl. I also felt that it was missing some bacon, but I tend to like "loaded" potato soups, so that could just be me. Adding bacon would probably ruin the lightness of the dish too. Nevertheless, I'll probably add it in next time.
