I have a soft spot in my heart belly for soups derived from other types of food. I had a bowl of mashed potato soup (w/ broccoli and cheddar) yesterday. I've had cheeseburger soup (if only it had been bacon cheeseburger soup). Baked potato soup (w/ sour cream and chives). Macaroni and cheese soup. Tortilla soup. Salisbury steak soup.
Flavors I am not looking forward to trying: belgian waffles soup, peanut butter and jelly soup, eggs benedict soup, chicken salad on rye soup, liver and onion soup, or bruschetta soup.
