Healthier Classic Macaroni Salad

4 cups whole wheat elbow macaroni

1 cup mayonnaise

¼ cup distilled white vinegar

⅓ cup white sugar

2 ½ tablespoons prepared yellow mustard

1 ½ teaspoons salt

½ teaspoon ground black pepper

1 large onion, chopped

2 stalks celery, chopped

1 green bell pepper, seeded and chopped

1 red bell pepper, seeded and chopped

¼ cup grated carrot

2 tablespoons chopped pimento peppers

Bring a large pot of lightly salted water to a boil. Cook elbow macaroni in boiling water, stirring occasionally until cooked through but firm to the bite, about 8 minutes. Rinse under cold water and drain.

Mix mayonnaise, vinegar, sugar, mustard, salt, and pepper together in a large bowl. Stir in onion, celery, green bell pepper, red bell pepper, carrot, pimentos, and macaroni. Refrigerate for at least 4 hours or overnight, before serving.
