Follow these easy steps to create your Classic Macaroni Salad with Ham:

1. Cook the Pasta: Bring a large pot of salted water to a boil. Add elbow macaroni and cook according to package instructions until al dente. Drain and rinse under cold water to stop the cooking process.

4. Combine Ingredients: In a large mixing bowl, combine the cooked pasta, diced ham, vegetables, and fresh peas. Gently fold in the dressing mixture until everything is well coated.
5. Taste and Adjust: Taste the salad and add extra salt and pepper as needed for flavor.
6. Chill: Cover and refrigerate for at least one hour, allowing the flavors to meld together.
7. Serve: Before serving, give the salad a gentle stir and garnish with chopped fresh parsley for a pop of color.
