This is my new favorite sandwich and I adore it. I think it would be perfect for a picnic although I haven't been on a picnic so far this fall because my life will not slow down long enough to fit one in.
Go on a picnic, okay?
You could certainly substitute regular balsamic vinegar if you can't find aged (I got mine at Publix). Don't leave it off, though, because it gives this sandwich a wonderful, tangy flavor.
I used an herbed foccacia bread for the sandwich pictured above, but I've also used ciabatta rolls. To me, the prosciutto is just an accent. Just one little slice is all you'll need for each sandwich. (Hello, Wayne County. Wal-mart has prosciutto now!)
Fresh Mozzarella Picnic Sandwiches with Artichokes, Prosciutto, and Balsamic Vinegar
Herbed Foccacia or ciabatta bread, split and cut into sandwich size slices
Aged balsamic vinegar
Fresh mozzarella slices
Thinly sliced prosciutto
Marinated artichokes, drained
Spring blend lettuce mix or arugula
Extra Virgin Olive oil
Freshly ground black pepper
Toast the bread underneath broiler until golden brown. Drizzle the cut sides of the bread with the balsamic vinegar. Layer the mozzarella, prosciutto, artichokes, and greens on the bottom half of the sandwich. Drizzle with olive oil and sprinkle with freshly ground black pepper. Top with remaining bread slice and wrap with deli paper or parchment paper.
