This is a tasty, quick, and easy dish to prepare when you have no time to plan for supper. This is so easy to prepare and will please a hungry group of children on a chilly day. You may substitute peas & carrots for the green beans if you prefer. You may also substitute ground lamb for the ground beef, or even leftover minced roasted beef/lamb (in which case just saute the onions alone and mix with the cooked meat). I usually use homemade leftover garlic mashed potatoes in this, but if all you have is instant, well - this is supposed to be a Lazy Mom's dish, so go ahead. I garnish this with a sprinkle of paprika if I am leaving out the cheese. Don't worry about the lack of salt & pepper in the meat - the soup provides all the seasonings and is the "secret" ingredient. Doubles well, and also can be made the day before, chilled and baked the next day for a hot lunch.
