Instructions
Preparation Steps
Bring a large pot of salted water to a boil. Cook rotini until al dente according to package directions, about 8 to 10 minutes. Drain, rinse under cold water to cool, shake off excess water, and toss with olive oil. Set aside to cool completely.
In a large mixing bowl, whisk together mayonnaise, Greek yogurt, Dijon mustard, lemon juice, dill, salt, and black pepper until smooth.
Add drained tuna, celery, red onion, peas, and pickle relish (if using) to the bowl. Fold gently to break up tuna into bite-size flakes.
Add cooled pasta and toss until evenly coated. If the dressing is too thick, loosen with a splash of cold water or a little extra lemon juice.
Fold in cherry tomatoes and shredded cheddar, if using. Taste and adjust salt, pepper, and lemon to preference.
Chill for 30 minutes for best flavor. Garnish with extra dill and serve cold.
Notes
Use any short pasta like macaroni or shells. For a richer salad, replace the yogurt with more mayo; for lighter, add extra yogurt and reduce mayo. Make up to 1 day ahead and keep refrigerated; stir and re-season with salt and lemon before serving. Store leftovers in an airtight container in the fridge for up to 3 days. Nutrition excludes optional cheddar and may vary based on brands.
