steaming keeps the salad light and fresh tasting-- evoking springtime-- whereas roasting would make it feel more wintry. i also disagree with the comments suggesting revising the salad dressing to double the honey. so when my local grocery only had a partial head of escarole grown together with green and red leaf in a head of living lettuce, i went with that. i think the tender young green and red leaf lettuces went well with the escarole. in order of preference, i would suggest as substitutes: young green and red leaf lettuces mixed with radicchio, butter lettuce, your basic spring mix.
