Well, I made up my own recipe and it was pretty darn good!
I chopped up some summer squash and green peppers and sauted in EVOO until tender then mixed with drained tuna, parm cheese, salt and pepper and put in a casserole dish and topped with crumbled melba toast. Then I baked at 350 for about 20 minutes.
My husband enjoyed it too, so I know it wasn't just me!
Thanks for all the responses!
