You might go down to the bookstore (used or mainstream) and browse through the cookbook selections. I'm sure there will be something that catches your eye that will have recipes you think your husband will eat.
You can also check out community cooking sites such as Recipezaar.com and allrecipes.com (there are tons of others, as well) and see what other people are cooking who may find themselves in your situation.
Finally, making even small adjustments in your habits will help. Omit or cut down on your use of salt, use olive or safflower oil instead of solid shortening, try oven frying instead of deep frying, and so on.
Good luck and good health!
