Mom's Dried Beef and Corn Casserole

This was my mom's favorite casserole when she was younger. However, she didn't get it very often because her brothers didn't like it as much. I like it, though, so I posted it! To make the dish less salty, rinse the beef in water before cooking. Also, cut down on the addition of salt in the recipe. (I find I need to do these things, to suit my tastes)
