Season the chicken. Pat the chicken dry. Rub with olive oil, salt, pepper, garlic powder, and smoked paprika.
Let it sit while you heat the pan or grill.
Cook the bacon. In a large skillet over medium heat, cook bacon until crisp, 8–10 minutes. Transfer to a paper towel–lined plate. Chop into bite-size pieces once cooled.
Sear or grill the chicken. Use the bacon drippings for extra flavor or add a splash of oil.
Cook chicken 5–7 minutes per side (thighs may take longer), until the center hits 165°F. Rest 5 minutes, then slice.
Make the dressing. In a bowl, whisk yogurt, mayo, Parmesan, lemon juice, Dijon, garlic, Worcestershire, and anchovy. Thin with water until pourable.
Season with salt and pepper. Taste and adjust lemon and Parmesan.
Prep the base. Chop romaine into bite-size pieces. Halve tomatoes.
Slice red onion if using. If adding grains, fluff and season them with a pinch of salt and a squeeze of lemon.
Assemble the bowls. Divide grains (if using) among bowls. Top with romaine, tomatoes, chicken, and bacon.
Add croutons and a generous sprinkle of Parmesan.
Dress and finish. Drizzle with Caesar dressing just before serving. Squeeze a lemon wedge over the top for brightness. Add extra black pepper for a classic Caesar vibe.
