Boil a large pot of salted water. Cook the pasta according to package instructions until al dente, about 8-10 minutes. Drain and rinse with cold water.

In a skillet over medium heat, cook bacon until crispy, about 7-10 minutes. Transfer to a paper towel-lined plate and chop into pieces.

In a large bowl, combine cooled pasta, bacon, peas, and parmesan. Gently fold ingredients together.

In a small bowl, whisk together mayonnaise, vinegar, salt, and pepper to make the dressing.

Pour the dressing over the salad mixture and toss gently to coat all ingredients.

Taste and adjust seasoning with additional salt and pepper.

Cover and refrigerate for at least 30 minutes before serving to allow flavors to meld.
