The only time I add salt when cooking is if I'm making pasta. Otherwise I could easily live without salt in my house. I don't add it to anything else that I cook, and I never salt food once it's done.

When I'm eating out, I use a lot of pepper, vinegar, and mustard, but no salt.

It's not a health thing, though - I just don't like the taste of whatever passes for salt these days (I don't mind "real" salt, but the lo-salt/healthy stuff places are using tastes disgusting IMO).
