Iceberg does at least have a good amount of vitamin K. :)
I like kale but only chopped up small. Other good alternatives are romaine and red leaf, often sold as "italian blend", arugula or spinach. If you want to simulate a wedge type salad, halving belgian endives is a good way to go.
My endeavors of late have been making soups, even if the weather is not feeling truly fallish yet. Last night I made butternut squash bisque with a garnish of sauteed bacon and shallots.
