Hamburger Noodle Casserole

This casserole has always been a family favorite and one of the first ones Mom taught me to make. I updated it to use whole wheat noodles and ground sirloin instead of ground beef. We always liked the noodles a little 'crunchy' on top. But, if you don't, just cover the casserole dish before baking.
