need good-tasting low-sodium ideas

For health reasons, I need to avoid salt/sodium. This can be difficult to do, as even foods you wouldn't normally associate with sodium have a lot of it in them (e.g., bread). I've got a couple of low salt/sodium cookbooks, but the recipes are too bland and unexciting. Has anyone else had to severely restrict their sodium intake? If so, have you found any good-tasting food? Not something that is "make do," like fakey-tasting low-sodium cheese, but actually good? I'd love some pasta sauce, salad dressing, and dip (for veggies) ideas, but anything that's tasty would be very welcome. Thanks for reading this.
