Berry, Lemon Chicken and Feta Salad

To assemble salads:Layer salad blend onto serving plates. Divide strawberries, blackberries, almonds, Feta and Parmesan cheese over salad. Top with grilled lemon chicken, sprinkle with lemon zest if desired. Drizzle top with poppy seed dressing. Serve immediately.For the grilled lemon chicken:Place chicken in a large resealable bag and pound thicker portions of chicken to an even thickness using the flat side of a meat mallet. In a mixing bowl whisk together lemon juice, lemon zest, olive oil, garlic, salt and pepper. Pour mixture over chicken in resealable bag, seal bag while pressing out as much excess air as possible. Move chicken around as needed to evenly distribute marinade and allow chicken to rest at room temperature for 20 minutes.Preheat a grill to moderately high heat. Brush grill grates lightly with oil and transfer chicken to grill (if you notice lemon zest and garlic sticking to one portion of the chicken more than another just brush it along the chicken to evenly distribute). Grill 6 - 8 minutes then rotate chicken to opposite side and grill until internal temperature of chicken registers 165 degrees on an instant read thermometer (total grill time will vary based on thickness of chicken breasts, so just be sure to check the temp for doneness). Transfer to a plate, cover with foil and allow to rest for 10 minutes, then slice into strips about 1/2-inch thick.Recipe Source: Cooking ClassyIn a mixing bowl, whisk together mayonnaise, sugar, apple cider vinegar, grated onion, mustard and salt until sugar has nearly dissolved (at this point you can transfer to a blender to mince onion pieces further if desired). Stir in poppy seeds. Transfer to an airtight container and refrigerate 30 minutes. Remove from refrigerator and stir (if you would like dressing to have a thinner consistency you can mix in a little milk 1 tsp at a time to thin). Store dressing in refrigerator.Recipe Source: Cooking Classy
