Boil the Pasta: Bring a large pot of salted water to a boil. Cook the elbow macaroni until it’s al dente, roughly 8-10 minutes. Drain it well and let it cool slightly.

Prepare the Dressing: In a mixing bowl, whisk together the mayonnaise, sour cream, freshly squeezed lime juice, and seasoning salt until the mixture is smooth and creamy.

Chop the Vegetables: While the macaroni cools, chop the red bell pepper, green onions, jalapeño (if using), and cilantro.

Combine Ingredients: In a large bowl, combine the cooled macaroni with the prepared chopped veggies. Pour in the creamy dressing and mix until everything is evenly coated.

Add Optional Ingredients: If desired, fold in the black beans and corn.

Chill the Salad: Cover the salad with plastic wrap and refrigerate for at least 30 minutes before serving.
