Which item includes a bed of jasmine rice as a base?

The item that includes a bed of jasmine rice as a base is the Korean shrimp bowl. This dish is designed to highlight the shrimp while providing a flavorful and aromatic bed of jasmine rice, which complements the seafood and other ingredients in the bowl. Jasmine rice is known for its fragrant aroma and slightly sticky texture, making it an excellent foundation for various toppings and sauces typically found in Asian-inspired cuisine.

This contrasts with the other options, which feature different types of bases or components. The club avocado chicken is more focused on a sandwich-style offering, the southwest salmon bowl usually incorporates other grains or mixed greens rather than a rice base, and Buster's bacon burger is fundamentally a traditional burger with no rice component at all. Therefore, the key distinguishing feature of the Korean shrimp bowl is its jasmine rice base, making it the correct answer.
