In a bowl, combine 1 cup plain Greek yogurt, 2 tablespoons fresh lemon juice, 2 tablespoons olive oil, 2 tablespoons Worcestershire sauce, ¼ cup grated parmesan cheese, 2 minced garlic cloves, ¼ teaspoon Kosher salt, and ¼ teaspoon pepper. Whisk until well combined and creamy. Store in the refrigerator to let the flavors meld.
Next, in a medium saucepan, whisk together ½ cup cornmeal or polenta, 1 ½ cups water, and ½ teaspoon Kosher salt. Cook over medium to medium-high heat, stirring almost constantly. Bring to a boil, then reduce heat and continue to cook for about 15 to 20 minutes until thick and sticky.
Once the polenta has reached the desired consistency, stir in 2 tablespoons grated parmesan cheese, ¼ teaspoon garlic powder, and ¼ teaspoon Italian seasoning for an extra kick. Remove from heat.
Transfer the polenta onto plastic wrap or a greased baking dish. Shape it into a rectangle about ½ inch thick, wrap in plastic wrap, and refrigerate until cooled.
Preheat your oven to 450°F. Cut the cooled polenta into ½ inch cubes and place them in a single layer on a baking sheet coated with olive oil or cooking spray. Spray the cubes with more olive oil and bake for 25 to 30 minutes, turning every 8 to 10 minutes, until they are browned and crispy. Set aside.
While the polenta bakes, pour ½ cup of the dressing over 1 lb thinly sliced chicken breasts. Marinate in the refrigerator for at least 30 minutes, allowing the flavors to infuse.
Preheat your grill to high heat. Once hot, place the marinated chicken on the grill. Reduce the heat to medium and grill for about 2 to 4 minutes per side, or until the chicken is cooked through, depending on thickness.
Remove the chicken from the grill and let it rest for a moment before slicing it into strips.
In a large bowl, toss together 8 cups chopped romaine lettuce and a few tablespoons of the dressing. Divide the lettuce among plates.
Top each plate of lettuce with the sliced chicken, 1 cup croutons, additional parmesan cheese, and more dressing if desired. Serve while fresh and enjoy your homemade Chicken Caesar Salad.
