I do this a lot with meal prepping veggies to be super easy to add to meals. Sometimes dinner is nothing more than cooking up some protein and adding veggies and condiments.
I have a bunch of chopped veggies and bagged lettuce in the refrigerator and do much the same. Today is tempeh, and tomorrow is the beans that are already soaking.
It's so easy to plan meals if you know in advance what protein you're having
No matter what the meal is, you know they have to be doing it buffet style. Trying to get that many plated meals out is a hell of a task unless you're a professional chef.
Lol 10-11 people is the only way I can see this working without spoilage. Just a single person or even a family of four would have to eat only salads or reduce the number of ingredients in the salad bar too keep it all from going had
It's a professional refrigerated salad bar, so I'd expect the same as you'd find in a restaurant. Maybe prep in the morning and dispose/repurpose into dinner in the evening. Such a cool idea, $1300 is a scary investment but it seems amazing.
