kind of depends on what else you have on hand.
chili is quick and easy
manwich/sloppy joes
cottage pie (if you have even canned or frozen veggies and some instant mashed potatos)
filled croissants (cook the meat with your choice of seasoning, put a good sized spoonful onto each pop and fresh croissant, roll and bake croisants according to regular directions). we've done this with taco seasoned-used salsa, guac. as toppings. done it with more of a stroganoff style of seasoning-used jarred brown gravy to top.
hamburgar soup-brown, season, add liquid (i use water, beef buillon cubes, red wine). chop up any fresh veggies hanging around (or if none-canned or frozen, but hold off till near the end of of cooking to prevent the veggies from getting mushy).
i had some stroganoff mix on the shelf recently and used it with ground beef-tastes the same, just a different consistancy.
