Bring a large pot of salted water to a boil and cook the rotini pasta according to package directions until al dente. While the pasta cooks, lay the bacon strips on a baking sheet and cook in a 400°F oven for about 12-15 minutes until crispy, or cook in a skillet over medium heat. Drain the pasta in a colander and spread it on a large sheet pan or bowl to cool while you prepare the other components. This parallel cooking saves time and lets both elements cool simultaneously.

Cut the chicken breasts into bite-sized cubes and season generously with salt and pepper. Heat a skillet over medium-high heat with a bit of oil, then add the chicken cubes and cook until golden brown and cooked through, about 8-10 minutes, stirring occasionally. Let the chicken cool to room temperature on a plate. I prefer cubing the chicken before cooking rather than after because it cooks more evenly and creates more surface area for browning.

In a medium bowl, whisk together the Greek yogurt and mayonnaise until smooth. Add the lemon juice, Worcestershire sauce, Dijon mustard, minced garlic, and freshly cracked black pepper, stirring until well combined. Fold in the minced fresh chives and finely shredded parmesan cheese, reserving a small handful of each for garnish if desired. Taste and adjust seasonings as needed—I like to add a tiny pinch more salt here to ensure the dressing has enough flavor to coat all the pasta components.

Once the bacon has cooled, break it into bite-sized pieces. In a large bowl, combine the cooled pasta from Step 1 with the cooked chicken from Step 2. Pour the Caesar dressing from Step 3 over the pasta and chicken, and toss gently but thoroughly until everything is evenly coated. Fold in the bacon pieces just before serving to keep them as crispy as possible. I've learned that adding bacon at the very end makes all the difference in maintaining that satisfying crunch.
