What sauce is commonly offered in the Cucina Mia selection?

The sauce most commonly featured in the Cucina Mia selection is Creamy Sun-Dried Tomato. This particular sauce stands out due to its unique combination of flavors, which balances the richness of creamy ingredients with the tangy and slightly sweet notes from sun-dried tomatoes. This sauce is a popular choice within the Cucina Mia line, where guests can customize their pasta dishes.

Other sauces like Alfredo, Marinara, and Pesto are also beloved at Olive Garden but are not as specifically highlighted within the Cucina Mia offerings. Alfredo is known for its richness and creamy texture, Marinara is a classic tomato-based sauce, and Pesto brings a fresh, herbaceous flavor, yet they do not define the Cucina Mia section as distinctly as Creamy Sun-Dried Tomato does. This makes the first choice the correct answer in the context of the question.
