I suspect that FROGGZ101 visited the "Fly Lady" as well.
When I need to peel or trim fresh veggies,
I wash them, then trim the scraps into a clean bowl. I then add the scraps to a ziplock bag: including pieces of bell pepper, peeling & ends of carrots, celery ends. I check my produce drawer at least a couple times a week. If anything isn't going to make it to the table in it's prime, I add it to my ziplock bag, which I store in the freezer. You don't need to precook these scraps.
I also add any left over herbs, especially the bay leaf that I fished out of my stew. If I have chicken bones, etc., I add them as well.
When the bag is full, I empty the contents into my crock pot. Fill it with water, and let it cook on low over night. The next morning, I strain the contents into a clean bowl. Chill this fresh & frugal veggie broth. Then package to freeze within 24 hours. If you don't have time to freeze right away, bring to a boil & simmer for 5 minutes to make sure there is no bacteria growing.
