Prepare whatever type of pasta you want (elbows, or spaghetti broken up a bit) in a casserole dish mix the following:

Tuna (two cans per pound of pasta)
Some kind of cream of whatever soup (one can)
A little water (1/4 of a can)

Mash these three things together.

Vegetables (peas and carrots are good)

Add the pasta to the mixture in the casserole dish and stir it all together. Add some bread crumbs to the top of all this and bake at 350 degrees until its hot and bubbly (the bread crumbs should brown also). That's all folks.
