I used about 2 cups of my leftover greenbean casserole, mixed with can of rotel, mixed together with slightly under cooked egg noodle. bake covered for 25min in 375 oven. Uncover top with more dried onions and bake til crispy brown about 10 min.
Made a dif casarole outta this for new years by subsituting ham for turkey and rice for noodles! It was very good! Ham rice greanbean casserole! ;)
