First off, history, I do ALL the grocery shopping AND all the cooking. Mrs. V does clean up which would be a GOOD deal if I wasn't so MESSY. That Said. I keep a couple of 2 Gal Freezer Bags in the Freezer (duh) and when I Lop the Bottom off of a "head" of Celery, or take the top and bottom off an onion with the first outer layer, Broccoli Bottoms, Asparagus Bottoms, Tops of Carrots, Cauliflower cores, Cabaage cores, ETC. Any Fresh Herbs that have almost run their course. Parsley Stems, Watercress Stems, etc. Any left over Bird Carcass' pieces etc. (Beer Can Chicken) Third piece off of Chicken wings. I just pop the stuff into the Freezer bag when I get the bags full I just pop in a few cloves of FRESH crushed Garlic, some Salt a Little Pepper, it never comes out the same but MAN - GOOD STUFF. Place stuff you would have tossed out into Stock Pot, Fill w water add spices and put on Med Low until it boils - then bring down to low simmer for a few hours. Strain out chunks, reserve Broth and then proceed to make your Soup. You WILL be a Happy Camper!
