Grilled-cheese fans are often divided into people who love the creamy, oozy insides and those who find the most joy in the crisped bits that ooze out and sizzle on the griddle. For those who prefer crunchy, the Cheese Toasties ($7.95) at Cowgirl Creamery's Ferry Building food stand are a dream come true. Thick slabs of Acme bread get a quick swipe of maple mustard and a layer of caramelized onions, all draped with thin panes of Cabot Clothbound cheddar that get quickly broiled open-faced in an oven. Served with a small salad to relieve you of complete guilt, each bite crackles with brittle shards of the cheddar, foiled by the sweetness of the onions and tang of the mustard.
