Cook Your Chicken: Season chicken with olive oil, garlic powder, smoked paprika, salt, and pepper. Air fry at 375°F for 12-15 minutes (or bake at 400°F for 20 min). Dice once cooled.
Crisp Up the Bacon: Cook bacon until crispy (air fryer or stovetop), then chop into bite-sized pieces.
Boil the Pasta: Cook pasta until just al dente. Rinse with cold water to stop the cooking.
Mix the Ranch Dressing: In a small bowl, whisk Greek yogurt, mayo, milk, ranch seasoning, and spices until smooth.
Toss It All Together: In a large bowl, mix pasta, chicken, bacon, tomatoes, cheese, and green onions. Drizzle on the ranch dressing and toss to coat. Garnish with parsley if desired.
