Directions

1. Prepare outdoor grill for direct grilling over medium heat.
2. From lemon, grate 1 teaspoon peel and squeeze 2 tablespoons juice. In small bowl, stir together lemon peel and juice, anchovies, garlic, mayonnaise, and 1/4 cup Parmesan. Set Caesar sauce aside. Makes about 1/2 cup.
3. Cut romaine heart lengthwise into quarters. Place romaine and any loose leaves on plate; drizzle with oil and sprinkle with 1/4 teaspoon salt.
4. In medium bowl, combine chicken, 1/2 teaspoon salt, 1/2 teaspoon pepper, and remaining Parmesan just until blended. Shape into four 3/4-inch-thick burgers. Spray both sides of burgers with nonstick spray.
5. Place burgers on hot grill rack; cook 12 to 14 minutes or just until meat loses its pink color throughout, turning over once. Burgers should reach internal temperature of 170 degrees F.
6. About 5 minutes before burgers are done, add romaine to grill rack. Grill about 5 minutes or until lightly browned and softened, turning occasionally and transferring romaine to platter as they are done.
7. Serve burgers on focaccia with romaine and Caesar sauce.
