Cook the chicken: Season chicken with salt, pepper, and a drizzle of olive oil. Grill or pan-sear over medium heat until cooked through and juices run clear (about 5–7 minutes per side for breasts, less for cutlets).
Let rest 5 minutes, then slice.
Make quick croutons (optional): Toss cubed bread with olive oil, salt, and pepper. Bake at 375°F (190°C) for 8–12 minutes, shaking once, until golden and crisp. Cool.
Whisk the dressing: In a bowl, combine Greek yogurt, lemon juice and zest, Dijon, Worcestershire, anchovy paste, minced garlic, and grated Parmesan.
Add a small splash of olive oil and a tiny bit of honey if using. Whisk until smooth. Thin with 1–3 tablespoons water or milk until creamy and pourable.
Taste and adjust salt, pepper, lemon, and garlic.
Prep the lettuce: Wash and dry romaine thoroughly. Chop or tear into bite-sized pieces. Wet lettuce waters down dressing, so get it dry.
Toss the salad: In a large bowl, add romaine and a generous amount of dressing.
Toss until leaves are lightly coated. Add more dressing if needed—coated, not soggy, is the goal.
Finish and serve: Top with sliced chicken, croutons, and plenty of shaved or grated Parmesan. Crack fresh black pepper over the top and serve right away.
