GROWN UP HAM AND CHEESE FINGER SANDWICHES

Steps:

• Preheat the oven to 400 degrees F.
• Bring water, vinegar and brown sugar to a boil. Add the onions and remove from the heat. Cover, and set aside until the onions come to room temperature.
• Trim the crusts off the bread and cut the bread into thirds, for 3 rectangles per piece. Lightly brush both sides of the bread pieces with olive oil and lay out on a baking sheet. Toast in the oven until just crisp and lightly brown, about 5 minutes. Cool.
• To assemble: Quarter, core, and very thinly slice the apple, (a mandolin is terrific for this). Very thinly slice the cheese into triangles or shards that will fit nicely on the bread.
• Place a dab or smear of mustard on the bread. Place a piece of apple, cheese and 1 or 2 sprigs of watercress on each piece of toasted bread. Wrap a small piece of prosciutto around each stack to make a neat package. Top with a little bit of the pickled onions, a drizzle of olive oil and freshly cracked black pepper. Serve at room temperature.
