Simple mass produced food recipes?

I often forget to eat while working or it happens that I can't be bothered to cook. While this might be an affront to r/recipes because of its simplistic and utilitarian nature, I need recipes for food that can be produced en masse and that's very easy to prepare and make. To give you an idea of what I mean: I had an idea for a large pot filled with blended vegetables and starches that can be stored in the refrigerator and made into patties in the oven. Simple. Easy to prepare. Easy to store. And easy to cook when needed.

 

Bleak, I know, but having something like this that's nutritious and filling that can be readily made is significantly better than ramen.

 

You do get bonus points if the recipe has in mind an exclusion diet :-)
