In addition to tonight's extravagant grilled sandwiches, I griddled a tray of portabella caps. The plan was to press them between heated plates, like the sandwiches, until they'd flattened and softened; then use them later in sandwiches or salads. Ha! Most are already gone. They're too tempting as snacks to be eaten out of hand. I do think they'd do better sliced first, if the plan is to use them in sandwiches.
