What is a popular protein alternative offered at Panda Express?

Tofu is a popular protein alternative offered at Panda Express as it provides a plant-based option that caters to vegetarians, vegans, and those seeking to reduce their meat consumption. Tofu is made from soybeans and is rich in protein while being low in calories, making it a nutritious choice. It is also versatile and absorbs flavors well, allowing it to be deliciously incorporated into various dishes at Panda Express, such as the Kung Pao Tofu. This aligns with growing trends towards healthier eating habits and the inclusion of more diverse dietary options on menus, making it a fitting alternative for customers looking for something different from traditional meat proteins. The mention of chicken, beef, and pork indicates more conventional meat options, which, while also popular, do not serve as alternatives in the context of plant-based diets.
