Shrimp Pasta Salad

Bring a large pot of salted water to a boil. Add shells and cook, stirring occasionally, until tender yet firm to the bite, about 9 minutes. Rinse pasta under cold water and drain.

Combine pasta, shrimp, pineapple tidbits, mayonnaise, tomatoes, cucumber, onion, garlic powder, and Italian seasoning in a large bowl and mix until well combined.
