Take any recipe for beef stew/casserole and make it using minced beef - similarly any recipe for lamb stew/casserole can be made using minced lamb. It will taste good but cost less money. You can also make meatballs using the mince plus flavourings - minced onion - breadcrumbs - egg to bind and then put these into any sauce such as curry or tomato or strogonoff.
Other things you can add are chopped root vegetables such as carrots - swede - parsnips.
