We're having Green Goddess dressing with crab cakes, but it also goes nicely with a salad of cooked chicken or shaved ham and asparagus. Use a sturdy lettuce like butter or romaine since the mayonnaise base gives it some weight.
For the crab cakes make sure to use Panko Japanese style bread crumbs. Conventional bread crumbs will result in a doughy cake. For the crab, a decent quality lump crab works well. But if money is no object go for the Dungeness.
