Open-Faced Grilled Tuscan Chicken Sandwiches with Fresh Mozzarella

4 tablespoons CARAPELLI® Extra Virgin Olive Oil, divided

1 tablespoon fresh lemon juice

2 cloves garlic, minced

3 teaspoons chopped fresh rosemary, divided

½ teaspoon coarse sea salt or kosher salt

¼ teaspoon freshly ground black pepper

4 (4 ounce) skinless, boneless chicken breast halves

4 slices rustic Italian or sourdough bread

1 cup packed baby greens or field greens

8 (1 ounce) slices fresh mozzarella cheese

Heat a grill to medium-high heat or have a ridged grill pan ready.

Combine 2 tablespoons of the oil, lemon juice, garlic, and 2 teaspoons of the rosemary in a small bowl. Sprinkle salt and pepper over chicken; place in a pie plate or shallow plate. Pour oil mixture over chicken; turn to coat. Let stand at least 10 minutes or up to 20 minutes.

Transfer chicken to grill with some of marinade clinging; discard marinade on plate. Grill chicken (or cook in a heated ridged grill pan over medium heat) 5 minutes per side or until chicken is no longer pink in center and internal temperature reaches 165 degrees F.

Brush remaining 2 tablespoons oil over both sides of bread. Place on grill (or in a large nonstick skillet) and cook 2 minutes per side or until golden brown. Transfer to serving plates; top with greens and cheese. Carve cooked chicken diagonally into 1/2-inch thick slices; arrange over cheese. Top with remaining 1 teaspoon rosemary.
