Keep a large plastic container in your freezer. A gallon jar with lid or a plastic ice cream bucket. Or even a large Zip lock bag will work. Instead of throwing away the celery leaves when you trim celery, tuck them into the container. That spoonful or two of leftover peas, corn, carrots, etc. Small amounts of meat or chicken when there is not enough to store in the fridge, a little leftover gravy, a dab of rice. Throw it all in there.
When the container gets full, put it into a large pot, add anything else that you would use if you were making a pot of vegetable soup, perhaps a can of tomatoes, more veggies. a couple cans of beef broth. Simmer slowly. If you have a large slow cooker, that would be a perfect vessel.
Have a good meal from it, and take any leftovers and pour a serving or two in a ziplock bag. Expel as much air as possible and seal, Lay the bags flat on a cookie sheet and freeze. When they are frozen stack them into a plastic shopping bag and set them on edge along the side of your freezer where it is easy to slide one out for a quick supper later on.
