My point is just that.

Vegetarian: do everything the same, just don't put meat in your dishes

Vegan: your whole paragraph.

You need to find substitutes for milk to benefit of the additives and need to try out. Took me a long time to find a milk substitute I like. Soy based stuff can cover for Calcium, but soy based stuff is rare in a lot of western diets, so you need to experiment.

That's my whole point. Certainly it is doable, but not as plug and play as a vegetarian diet. And, when you don't try the stuff mentioned in your paragraph and mine, you might run into issues, especially with children. That's what I am saying, that's a subjunctive.
