Olive Garden offers which type of drink as a smoothie?

The correct answer is that Olive Garden offers non-carbonated drinks as smoothies. Smoothies are typically made by blending fruits, vegetables, and other non-carbonated ingredients, creating a creamy and thick texture without bubbles. This aligns with the general preparation and serving style of smoothies that do not include carbonated beverages.

In this context, "non-carbonated" effectively captures the essence of what a smoothie is, as it consists of blended ingredients rather than carbonated elements. Smoothies also prioritize a refreshing and nutritious quality, focused on delivering flavors that derive from fruits or dairy, further solidifying why non-carbonated is the appropriate choice here.
