Which of the following is NOT a side item at Texas Roadhouse?

The correct choice is cornbread, as it is typically served as a complimentary bread item rather than a side dish at Texas Roadhouse. While patrons often enjoy cornbread alongside their meals, it is categorized as a bread option that accompanies the main courses, rather than a standard side item. On the other hand, steamed veggies, sweet potato, and mashed potatoes are all recognized as side items on the menu, allowing diners to choose from a variety of accompaniments to their main dishes. Each of these side items adds unique flavors and textures to the meal, which enhances the overall dining experience.
