The list of easy to eat foods will help. Its full of smoother textured foods which are easier to swallow than say cookies or
crackers.
Easy to Eat Foods Im also very limited with my eating. Yes it sure gets old always eating the same things. I try to switch mine up by alternating weeks where I will eat raspberry jello, homemade chocolate pudding, homemade strawberry cheese pie (no berries or crust), and home made tapioca pudding. I will eat a bowl of one of those things with lots of whipped cream. That gives me some variety. But every single day I will eat cream of wheat (which is my main meal) and a couple peach flavored blended yogurts. Since your husband has problems with tasting sweet, omit the sugar if making any of the above foods from scratch and maybe he will like it better.
As far as his salivia goes, has he tried pilocarpine or salagen? Those are a couple medications which help to produce saliva. They do take a few weeks to fully work but it may help him. Members have had varying results with those medication. I didnt like it as they made me sweat profusely (which girls dont do! LOL!). But others have found success with them. Its worth a shot. Good luck!!!
