There’s some muscle behind this salad fast casual. This winter, Panda Express acquired 33% of the company and is advising its expansion. The chain also is building out its technology, teaming up with subscription lunch program MealPass and rolling out an app with mobile payment. Just Salad stokes its street cred as an environmentally conscious restaurant with reusable branded salad bowls, which customers can bring in to score free toppings.
