Which of the following dishes is typically considered a staple in Italian cuisine?

The option that is considered a staple in Italian cuisine is Vegetarian Pasta Primavera. This dish exemplifies classic Italian cooking through its use of fresh, seasonal vegetables combined with pasta, which is a core component of many Italian meals. Pasta is a significant part of Italian culinary tradition, and Primavera, meaning "spring," reflects the use of fresh vegetables that showcase an important aspect of the Italian emphasis on fresh, high-quality ingredients.

The other dishes listed, such as quesadilla and sushi, while popular in their respective cultures (Mexican and Japanese), do not represent Italian cuisine. Chicken Tikka Masala, although beloved and widely recognized, is a dish from Indian cuisine. Therefore, Vegetarian Pasta Primavera stands out as a true representative of Italy's rich culinary heritage.
