Extremely frugal Cooking tip: Saving veggi scraps

I am on an extreme budget for groceries, so I never buy more vegetables than what I need, and I am always looking for ways to stretch my food for recipes. I came up with this tip:

Save your vegetable scraps. Save the tops and ends of carrots, save the tops of onions or bell peppers, and save the tops of celery, and those tiny soft sticks in the center you never eat. Keep them in a zip top bag through the week or two weeks, if your veggies will keep that long. At the end of the week, toss this bag in some water to make a veggie broth for soups. Broths are so low maintenance! I through mine in a crock pot over night with some chicken bones (from chicken breast that I took the bones out myself) add seasonings, and tada! You have a broth to freeze for later or use for a healthy lunch or dinner. Broths don't have to be just for soup! Use them in the place of water when making rice or other savory recipes.

I also like to save the tops of my tomatoes for an at home tomato scrub I saw on youtube!
