I have never added salt to any meal in my life. However, I eat mostly processed foods which are high in salt. I don't cook anything ever and don't plan to start. I wish the canned foods I eat had less salt but they don't.
There are alternatives that are lower sodium and don't require cooking beyond heating stuff in a microwave or oven. These are ideas. Some may not work for you but it may give you an idea of what can.
1. Rotisserie chicken - I eat this removing skin which is where a lot of the seasonings are located. Very easy. Sometimes I just eat the chicken by itself. Other times I make a salad. When I want a little more flavor I put just a little BBQ sauce on it. It is cheaper to cook the whole chicken yourself and is easy. But, honestly, the difference in cost is not that much so the already cooked is fine.
2. Frozen already cooked chicken breasts (or fish or whatever). I have bought from Walmart their already cooked frozen chicken breast. It has a little more sodium than if I bought raw and cooked it myself but it is not bad at all. These can be microwaved or baked. Very easy as they are already cooked. They also come in other brands and flavors.
3. Frozen vegetables. Plain frozen vegetables have very little sodium. Even if you like with some sort of flavoring it is minimal. These you can just stick in the microwave and heat.
4. Eggs - If you don't want to hardboil themselves (a Dash egg cooker is very cheap extremely simple. You just basically put the eggs in and plug it in. But, again, you can buy already cooked hardboiled eggs and that reduces sodium again.
5. Salads - You may not like putting salads together but it is easy especially if you buy already bagged greens and already chopped vegetables. If you don't want to do that buy the already made salads. There is some sodium but not as much as a lot of meals. You can also do your own salad dressing that has no sodium. I often use a mix of 3 T. of lemon juice (the kind that is refrigerated) and 1 T. olive oil. I just put them each on the salad and then mix it. Very easy.
6. Do you eat bread? If so usually what you get from the bakery has less sodium. If you eat tortillas buy them freshly made. No cooking required.
7. Fresh fruit -- I don't love fruit but I have blueberries for breakfast. No sodium. Other people like bananas (I don't) and other fresh fruit.
8. Nuts unsalted. I have unsalted almonds with my blueberries and it is very good and low sodium.
9. For an easy small meal that is lower sodium I often have a Quest bar. There are other brands but look for something that has say under 250 mg of sodium.
10. Many products do come in a lower sodium version. Check that out.
11. Some brands of frozen meals are better overall on sodium. Look at the labels.
12. A lot of cheese products are low sodium.
Now on the issue of cooking. I can cook but I don't love doing it. But, I have been willing to....assemble. That is, I can assemble a salad. It is easy.
Something that is just a step past that is making a frittata. I can cooked some frozen stir fry veggies in the microwave. Dump those in a small skillet. Mix some eggs and some already shredded cheese. Poor over the eggs. Add any cooked chicken if I want to. Put it on low and cook it 10 minutes. Done. Even I can do that. If it is a large frittata I can get 4 meals out of it (they can be frozen and just microwaved later on).
There are a lot of very simple things like that which help. I would rather cook something that will last for 4 days so I don't have to do it often.
Another assembling one. Packets of tuna fish (again, already cooked). Mix with mayo, chopped up hardboiled eggs (you can buy those already cooked if you want). There, I have a tuna fish salad. I can eat alone or make a sandwich.
