Ingredients

Instructions

  1. Step 1: Preheat a grill pan over medium heat. Brush 2 large slices of ciabatta bread with 1 tbsp olive oil on one side each.
  2. Step 2: Spread 2 tbsp basil pesto evenly on the un-oiled side of each bread slice. Layer 4 oz sliced fresh mozzarella, 1 medium sliced tomato, and 10 fresh basil leaves on one slice. Sprinkle 1/4 tsp salt and 1/4 tsp freshly ground black pepper over the tomato.
  3. Step 3: Close the sandwich with the other bread slice, pesto side down. Place the sandwich on the grill pan, pressing lightly, and grill for 3-4 minutes per side until the bread is golden and the cheese begins to melt.
  4. Step 4: Meanwhile, pour 2 tbsp aged balsamic vinegar into a small saucepan and simmer over low heat for 5-6 minutes until reduced by half and syrupy.
  5. Step 5: Remove the sandwich from the pan, slice in half, and drizzle generously with the aged balsamic reduction before serving.
