Cook the pasta according to package instructions until al dente. Drain and rinse under cold water.
In a large mixing bowl, whisk together mayonnaise, Greek yogurt, Dijon mustard, garlic powder, onion powder, salt, and black pepper.
Add the drained tuna, celery, red bell pepper, red onion, dill pickles, and lemon juice to the bowl.
Toss the mixture until well combined.
Fold in the cooked pasta and mix gently to coat evenly.
Garnish with fresh parsley and refrigerate for at least 30 minutes before serving.
Serve chilled and enjoy!
