MAKE THE DRESSING: In a bowl, whisk together mayonnaise, buttermilk, lemon juice, Worcestershire sauce, minced garlic, yellow mustard, anchovy paste, dried parsley, and black pepper until smooth and creamy. Stir in the grated Parmesan cheese, then cover and refrigerate while you prepare the rest.
PREPARE THE CHICKEN: In another bowl, combine the ground chicken with Italian seasoning, lemon pepper, garlic powder, onion powder, salt, and black pepper. Mix until just combined.
To each tortilla, add about ¼ cup of the chicken mixture and press it out to evenly cover the entire surface. Add more if you prefer a thicker patty. Tip: If the chicken sticks while pressing, lightly coat your fingers or spatula with a little oil to help spread it smoothly.
COOK THE TACOS: Heat a skillet or pan over medium-high heat with a small splash of oil or dab of butter.
Place the tacos meat-side down in the pan, working in batches if needed. Cook for 2 to 3 minutes until the meat develops a golden crust. Flip the tacos, lower the heat, and let the tortilla crisp up for another 2 to 3 minutes until the chicken is fully cooked. Remove and repeat with the remaining tacos.
ASSEMBLE THE TACOS: In a bowl, toss the shredded romaine with some of the Caesar dressing—use as much or as little dressing as you like. Add the crushed croutons and toss again.
Top each taco with the dressed salad mix, extra Parmesan cheese, a sprinkle of chopped parsley, and another drizzle of Caesar dressing on top if you want it extra saucy. Enjoy warm!
