Cook the pasta: Bring a large pot of salted water to a boil. Cook the pasta until just al dente. Drain, rinse under cool water to stop the cooking, and toss with a splash of olive oil so it doesn’t stick.
Season the chicken: Pat the chicken dry.
In a small bowl, mix smoked paprika, onion powder, garlic powder, salt, and pepper. Rub evenly over the chicken.
Sear and cook the chicken: Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add chicken and cook 4–6 minutes per side, until cooked through and nicely browned.
Splash in 1 teaspoon Worcestershire during the last minute to glaze. Transfer to a plate to rest, then slice or dice.
Sauté peppers and onions: In the same pan, add the sliced peppers and onion with a pinch of salt. Cook over medium heat, stirring, until softened with a little char, 6–8 minutes.
Stir in the garlic for 30 seconds. Add another 1 teaspoon Worcestershire and the red pepper flakes, if using. Remove from heat and let cool slightly.
Make the dressing: In a bowl, whisk Greek yogurt, light mayo, cream cheese or blended cottage cheese (if using), Dijon, vinegar, lemon juice, and 1 tablespoon olive oil.
Season with salt and pepper to taste. You want a tangy, creamy dressing that clings to the pasta.
Combine: In a large mixing bowl, add cooled pasta, chicken, peppers and onions, and provolone. Pour over the dressing.
Toss gently until everything is coated and glossy.
Taste and adjust: Add more salt, pepper, vinegar, or lemon as needed. The peppers should pop, and the dressing should be bright but creamy.
Chill or serve: Garnish with chopped parsley. You can serve right away slightly warm, or chill for 30–60 minutes to let flavors meld.
