This is a recipe that has been used in my family for generations -- sounds different but really i quite good

Hash - in a meat grinder grind up leftover roast and any vegetables that may be left -- to make it stretch add additional potatoes, carrots, and another onion--- assuming you have leftover gravy -- after everything has been ground add the gravy and in a frying pan fry the mixture in a small amount of crisco. Let it brown on one side and begin turning - kinda like making home fries at this point - try not to add any more grease. --

Hope you like this as much as our family does.
