Anyone have any suggestions for things that are good to eat that are both low in sodium and low in carbs?

I recently found out I have diabetes and high blood pressure (and congestive heart failure.) I have lost 30 pounds, and hope to lose about 30 more.

I am trying to have a varied diet, but it’s hard to find things I can eat that meet my requirements. I don’t a whole lot of “complicated” cooking either, so I am looking for more simple solutions. Any helpful suggestions would be appreciated…
