Bring a pot of salted water to a boil and cook the pasta according to package directions until just tender. Drain well in a colander and set aside to cool slightly. I prefer rotini or fusilli here because their spiral shape catches the creamy dressing beautifully and holds all those delicious flavors in every bite.

While the pasta cooks, heat a skillet over medium-high heat and add the ground beef, breaking it apart as it browns. Once the beef is mostly cooked through (about 4-5 minutes), sprinkle in the taco seasoning and stir well to coat. Cook for another minute until fragrant, then transfer to a plate to cool slightly.

In a large mixing bowl, combine the mayonnaise, sour cream, chipotle seasoning, smoked paprika, and freshly squeezed lime juice. Whisk together until smooth and well blended, creating a cohesive base for all the other flavors. This dressing is the backbone of the salad, so take a moment to ensure everything is fully incorporated.

Add the cooled pasta from Step 1 and the cooked beef from Step 2 to the dressing bowl. Toss everything together thoroughly, making sure the dressing coats all the pasta evenly. This is when the flavors start coming together, and I like to taste at this point to see if the seasoning balance feels right before adding the fresh vegetables.

Fold in the diced tomato, coriander, jalapeños, corn, and black beans into the salad. Use a gentle hand when stirring to avoid breaking up the vegetables too much while ensuring everything is evenly distributed. For fresher, brighter flavors, add these ingredients right before serving rather than mixing ahead of time, as the acidity from the lime juice can soften the vegetables if left to sit too long.

Transfer the fiesta pasta salad to a serving bowl or plate and enjoy immediately while all the textures and temperatures are at their best. The combination of warm beef, cool pasta, and fresh vegetables creates a perfectly balanced high-protein meal.
