Hi
For me bland and soft worked best. no tomato based dishes for me.
Canned macaroni cheese, just warm, cheese omelets with lots of butter to help them slide down, mashed potato with butter, I'm not a gravy person, I kept away from fruit juices for a while but peach juice was the most gentle to start.
Try to think maximum calories per swallow, if you can tolerate canned soups stir in some cream or whole milk powder, it will get better with time.
Sunshine.. love and hugs
