Begin by bringing a large pot of salted water to a rolling boil over high heat. Add the medium shells pasta and cook for about 7-8 minutes, or until al dente. Once cooked, drain the pasta thoroughly in a colander and rinse it under cold running water to cool it down.

In a spacious mixing bowl, combine the cooled pasta with imitation crab, thawed peas, chopped red onion, diced celery, and red bell pepper. Gently fold these ingredients together to avoid breaking the imitation crab.

Stir in the mayonnaise and fresh dill to create a creamy and colorful Crab Pasta Salad.

Add salt and pepper to taste, mixing it well to ensure every component is seasoned perfectly. Cover the bowl with plastic wrap or a lid, then refrigerate the salad for at least 1 hour.

Once chilled, serve the Crab Pasta Salad cold in individual bowls or on a platter, garnishing with fresh chives.
