Step 1: Cook the Pasta : Bring a large pot of salted water to a boil. Add pasta and cook until al dente (usually 8–10 minutes, depending on type). Drain and rinse under cold water to stop the cooking process. Set aside to cool completely.
Step 2: Prepare the Dressing ; In a mixing bowl, combine mayonnaise, Greek yogurt, Dijon mustard, lemon juice, honey, garlic powder, salt, and pepper. Whisk until smooth and creamy. Taste and adjust seasoning — add more lemon juice for tang or more honey for a hint of sweetness.
Step 3: Assemble the Salad : In a large salad bowl, add cooled pasta, drained tuna, celery, onion, red bell pepper, peas, and herbs. Pour the creamy dressing over the mixture. Toss gently with a large spoon until everything is evenly coated. Taste and season with salt and pepper as needed.
Step 4: Chill Before Serving : Cover the bowl with plastic wrap. Refrigerate for at least 30 minutes to let the flavors meld together. Serve chilled.
