Prepare the Chicken:In a bowl, mix 2 tbsp olive oil, 1 tbsp lemon juice, 1 minced garlic clove, oregano, salt, and pepper. Coat the chicken breasts and marinate for 15–30 minutes. Grill or bake at 375°F (190°C) for 12–15 minutes until the internal temperature reaches 165°F (74°C). Let rest, then slice thinly.
Make the Caesar Dressing:In a small bowl or blender, combine ¼ cup olive oil, 1 tbsp lemon juice, 1 minced garlic clove, anchovy paste, Dijon mustard, and Greek yogurt. Whisk or blend until smooth. Add 2 tbsp grated Parmesan, salt, and pepper to taste. Adjust with more lemon juice if needed.
Craft Homemade Croutons (Optional):Preheat oven to 350°F (175°C). Cube rustic bread into 1-inch pieces, toss with 1 tbsp olive oil, salt, and a pinch of garlic powder. Spread on a baking sheet and bake for 10–12 minutes until golden and crispy.
Assemble the Salad:In a large bowl, toss chopped romaine with the dressing until evenly coated. Top with sliced chicken, croutons, and shaved Parmesan. Serve immediately for maximum crunch.
