What additional ingredient does the Cajun Jambalaya Pasta contain alongside tomatoes and onions?

The Cajun Jambalaya Pasta is known for its rich and bold flavors, which come from a combination of several classic ingredients. One of the key components, alongside tomatoes and onions, is peppers. Peppers add a distinct sweetness and a touch of spiciness that enhances the overall flavor profile of the dish, creating a balance that complements the Cajun seasoning.

In the context of Cajun and Creole cooking, peppers are often used to build the "holy trinity" of flavors, alongside onions and celery, which forms the base of many dishes. Thus, the inclusion of peppers in the Cajun Jambalaya Pasta is essential as it aligns with traditional ingredients found in such recipes, contributing to the depth and authenticity of the dish.

The other options, while common in various recipes, do not play a significant role in the classic Cajun Jambalaya Pasta as peppers do, and therefore, do not contribute to the specific flavor and texture sought in this dish.
