Tuna Macaroni Salad is a classic potluck recipe and is so easy to throw together. It is creamy and delicious with lots of hard-boiled egg, peas, celery, onion, and sweet pickle relish.
Bring a pot of salted water to a boil. Cook pasta according to package directions, adding the peas the last minute of cooking time. Drain and rinse under cold water. Drain again and add to a large bowl.
Add remaining ingredients and stir to mix.
Refrigerate until ready to serve. Can be made a day in advance.
