Reply #3: I've done that

Freeze dried vegetables are dehydrated in a vacuum chamber and retain most of their nutrients. Dehydrated vegetables (not treated with sulfities) can lose some of their vitamin A and C nutrients. Blanching (as you would do before freezing) the vegetables also causes loss of nutrients. Nothing is as good as fresh veggies - but the freeze dried and dehydrated vegetables probably are comparable to frozen and canned vegetables in nutritional content.

You will note that the veggies I named are typically used to season and impart flavor and aroma. And that is how I intend to use them - as supplements to other foods.
