I make stew out of anything I cook
When I'm cooking for just myself there's always leftovers, so if I roast a chicken or a beef roast or bison roast, I will make sandwiches for a few days and then cut up the rest and throw it in the slow cooker with some veggies and spices!
My mom makes delicious hamburger soup but I've never tried to make it. I always have enough in my freezer from her!
