Basic Creamed Tuna on Toast Recipe. I have not tried this, but it sounds like what you're looking for.

I love making this. Only difference, is that I add a little milk to the soup (about 1/2 cup) to thin it out a little. I also add some pepper and garlic powder to it while cooking. And I DEFINITELY add the peas - they make the dish. It's good on toast, or on rice. Yum.
