Throwing someone to a 3D Zelda for the first time might be too much for him/her, I know that just too well. Is too complex for some people. I would start with a 2D game, but not something hard like the first Zelda or ALttP. It shouldn't be too outdated visually speaking, some people don't like that unless they already love a series. Also, it shouldn't be too long to beat. You have to think about this first contact as a "demo", he has to realize if he likes it or not, so you can't give that person a 25-30 hour game to the face.
I think the best ones to start are A Link Between Worlds and Minish Cap. I started with Minish Cap and now I'm a great Zelda fan.
