Making Creamy Pasta Salad is straightforward when you follow these easy steps:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Add the pasta and cook according to package instructions until al dente. Drain and rinse under cold water to stop the cooking process.
2. Prepare the Dressing: In a large mixing bowl, combine mayonnaise, sour cream, Dijon mustard, apple cider vinegar, garlic powder, onion powder, salt, and black pepper. Mix well until creamy and smooth.
3. Combine Ingredients: Add the cooled pasta to the dressing and mix until the pasta is evenly coated.
4. Add Vegetables: Gently fold in the diced celery, bell pepper, cherry tomatoes, shredded carrots, and thawed peas. Ensure everything is well combined.
5. Chill: Cover the salad with plastic wrap or a lid, then refrigerate for at least 30 minutes. This allows the flavors to meld beautifully.
6. Serve: Before serving, give the salad a gentle stir. Garnish with chopped green onions or fresh parsley for an added touch.

With these steps, creating a delicious Creamy Pasta Salad is effortless!
