Meat Based Vegan Foods

Let's say you had to take care of a small child or senike elder adult who out of the blue insisted on a vegetarian diet, but were unfamiliar with vegetables (as would be the case if I was feeding them prior). Are there any recipes on disguising meat as vegetables? It is important to maintain their health, so they need to eat meat, red meat, white meat, dark meat.

All I can find is Arby's made a carrot out of Turkey once. There is a moral and ethical imperative to make sure they are eating right.
