One of my favorite things to do in the whole entire world is to save the vegetables from throwing parties and make soup the next day. When you throw a party, you HAVE to have a veggie tray. It just screams, "See! I'm a healthy person! I'll provide you with healthy treats."
Reusing veggie platters in soup is especially easy to do if you stick to carrots and celery. And you must use the crockpot. That's just what you do. There always seems to be leftover vegetables from vegetable trays at my house. Guess my friends just aren't very healthy. That is fine. Some people just throw leftovers away - but not cheap people. We must reuse!
