I'd simply avoid all processed junk whenever possible while staying away from restaurant foods except for those special occasions. Most likely that should get about three-quarters of the game covered according to this chart below:
For the meals that were prepared on my own, no added salt whatsoever since the flavor would come from salt-free canned tomatoes and powdered white onion. Maybe I would sprinkle just a little bit of kelp granules on top whenever I felt like adding a little bit of taste.
Stuff like chili garlic sauce and canned soups do contain some salt, I would add water to dilute them as my condiments while mixing everything beans and rice:

Well below my 1,500mg/day target and I don't really think much about my sodium intake as long as I'm cooking everything myself.
BTW, there are quite a few substitutes out there and three of them could be found online.

Jeff Novick made this chart a few years ago, that should tell us where do we stand:
