What is a key aspect of Panda Express' menu development?

A key aspect of Panda Express' menu development is the incorporation of fresh ingredients and bold flavors. This focus on freshness and flavor is fundamental to the brand's identity, as it seeks to deliver authentic Chinese cuisine with a unique American twist. By using high-quality, fresh ingredients, Panda Express ensures that its dishes not only taste great but also maintain a level of freshness that appeals to customers seeking a satisfying and flavorful dining experience.

In contrast, the other options do not align with the brand’s commitment to quality and innovation. Using pre-packaged ingredients would not support the goal of offering fresh and distinct flavors. A sole focus on low-calorie meals would limit the diverse offerings that characterize Panda Express' menu and could exclude many of the bold, flavorful dishes that customers enjoy. Additionally, limiting the variety of dishes would restrict menu creativity and the ability to cater to a wide range of tastes, which is contrary to the brand's strategy of providing an extensive selection that embodies various flavors.
