What is sushi in walmart?

As an AI language model, I don't have access to real-time information on Walmart's sushi offerings. However, according to online sources and customer reviews, Walmart generally offers pre-packaged sushi that is made fresh each day or supplied to the store from a third-party vendor. The sushi options include traditional sushi rolls like California, tuna, and salmon, as well as a selection of specialty rolls. Some Walmart stores also offer freshly made sushi available at their in-store deli counters. The prices range between $5 and $15 depending on the type of sushi and location. As with any food purchase, it's essential to make sure the product is fresh, and you should always check the ingredient list for allergens or dietary restrictions.
