Step 1

Cook pasta in a large pot of salted water until al dente. Drain and rinse under cold water. Transfer to a large bowl.

Step 2

While the pasta cooks, prepare the dressing by combining mayonnaise, olive oil, lemon zest and juice, salt, pepper, and garlic powder in a small bowl. Stir with a whisk until smooth.

Step 3

To the bowl with pasta, add remaining pasta salad ingredients: tomatoes, green peas, red onion, celery, olives, chives, and dill. Pour dressing overtop and toss to combine. Serve immediately or cover and refrigerate until later use.
