I consider the smoothie I make in a large Vita-Mix that lasts up to 3 days one of my most nutritious meals. That smoothie and a huge salad that also lasts days are the basic infrastructure of my overall diet, as they are both done virtually every week.
The ingredients that go into this smoothie have been added incrementally over the years so that now making one is quite a complex operation where I have to keep many things in store and ready to add. The same is true of the salad, but with the salad there is much more variability, as I like to eat at least a slightly different version each time. Here using different dressings helps that variability.
I think most people should do the same, that is, develop a complex and super nutritious smoothie as well as a complex and super nutritious salad, and make these two staples the mainstay of your diet.
