Salt free

My husband always loved my cooking. What meals we used to have. Scalloped potatoes, quiche, german potatoes, baked beans. All of these were served with ham or bacon or sugar and of course salted to taste.
Then in 2005 things changed. My new diet suddenly consisted of maximum 800mg of salt a day and a huge reduction in sugar.
We had driven about 300 miles on our first holiday in 10 years when I became concerned that I hadn't urinated in quite some time. When I casually admitted this to my hubby his helpful comments were, "it probably had something to do with hating this province and wanting to go home". However , being a considerate husband he did compromise by getting a motel room and purchasing KFC and a big jug of root beer. This did not seem to alleviate the problem as I started to swell and still could not urinate. I had heard that when something like this happens you just need to get some water pills. What a surprise when the pharmacist informed us that these were by prescription and that we should see our doctor. My husband of course considers himself smarter than the average pharmacist and decided I was dehydrated. Our vacation would not be canceled but instead I would drink copious amounts of water. Who ever heard of drinking 3 gallons of water and not peeing ? He even suggested beer as this always makes him go. I resisted and we headed home.
My Doctor sounded alarmed at my symptoms and sent me directly to the hospital. My husband actually looked worried but I assured him the doctor was just being careful. Probably a few tests and send me home. Two weeks of hospital stay later we started to realize it may be more than dehydration or my dislike of the unnamed province's scenery. I even at one point confessed that my life may not be that long.
I was diagnosed with a disease called diffuse IGAN with acute nephritis. I have no idea what this meant other than I had a disease that attacked my kidneys. The doctors did assure my husband that if we continued our trip I could have died. Neither of us had ever been seriously ill before so we had no idea how this disease would change our life. I did get my water pills but that was only a part. There were drastic diet changes and the dreaded PREDNISONE and in large doses.
Prednisone can't be that bad we thought. It was quite cheap. Sure the side effects were a bit disheartening (may cause skin to thin, may cause face to become moon shaped,  may cause loss of hair where you want it and excess hair where you don't) but I have seen bad side effects on bottle of antacid. Due to my high dosage over a period of six months I managed to get all the side effects plus.
 So now how do I cook a meal that is tasty considering I no longer have operating taste buds and how do I convince my husband that he too needs to change his taste to a low salt diet.
