Have you really tried all the different vegetables out there? And like none but cucumbers? I find that hard to believe...
If anything dry is out of question, how to you manage to have bread with every lunch? Bread is very dry, isn't it?
How about making soup? It's not dry, you can make a meaty broth, as you seem to like meat, then add some veggies and if the whole thing doesn't appeal to you, blend it, so you get a nice creamy soup. Easy to swallow, and it can be any taste you like. And you can prepare a lot of it and freeze it in portions.
I also second the dairy suggestion - some cottage cheese, joghurt, cream cheese with veggies or fruit is a great meal with plenty of protein.
And for your dinner, as Susan said, just skip the potatoes and have more veggies instead. It's easy and healthy.
