Thaw the frozen peas at room temperature for 10-15 minutes or rinse under cool water. Drain and set aside.

In a separate bowl, whisk together mayonnaise, sour cream, salt, and black pepper until smooth.

In a large bowl, combine the thawed peas, cheddar cheese, red onion, hard-boiled eggs, and bacon bits. Mix gently.

Pour the dressing over the salad ingredients and fold until well-coated.

Cover and refrigerate for at least 30 minutes to let flavors meld.

Gently stir before serving and garnish with dill or parsley.
