This Easy Chicken Caprese Sandwich is filled with fresh veggies and chicken packed with flavor. The balsamic marinade gives the chicken a tangy punch making it great for summer!
In a large bowl, mix together 4 Tablespoons olive oil, parsley, lemon juice, and balsamic vinegar.
Place a single chicken breast inside of a ziplock bag (or between two sheets of saran wrap). Using a mallet or rolling pin, pound chicken to 1/4 inch thickness, set aside. Repeat with the other three chicken breasts.
Place the chicken into bowl with the olive oil mixture, let the chicken marinate at room temperature for approximately 10-15 minutes.
Set a large skillet to medium high heat. Add the chicken to the pan and cook undisturbed for 3-5 minutes, flip and repeat with opposite side. Make sure the chicken reaches an internal temperature of 165° Fahrenheit.
While chicken is cooking, drizzle the remaining olive oil on each side of the ciabatta roll. Place in broiler for 5 minutes or until crispy and browned.
TO STORE LEFTOVERS: Leftover chicken can be stored in the refrigerator for up to 3-4 days in an airtight container. Best if wrapped tightly in plastic wrap.
