Cook the pasta according to the package instructions. Drain and rinse with cold water to stop the cooking process and cool the pasta down.
While the pasta is cooking, prepare the dressing by whisking together the olive oil, lime juice, honey, dijon mustard, minced garlic, salt, and pepper in a small bowl.
In a large mixing bowl, combine the cooked and cooled pasta, diced mango, diced bell peppers, diced red onion, and chopped cilantro.
Add the cooked and peeled shrimp to the mixing bowl, then pour the dressing over the top of the pasta salad.
Gently toss everything together until the pasta and vegetables are evenly coated with the dressing.
Cover the pasta salad and refrigerate it for at least an hour, or up to 24 hours, to allow the flavors to meld.
When you're ready to serve, give the pasta salad a good stir and taste for seasoning. If needed, add a pinch of salt or a squeeze of lime juice to brighten up the flavors.
Serve the pasta salad chilled or at room temperature, garnished with a few sprigs of fresh cilantro if desired.
