Save time and money on dinners!

I have been trying to figure out a way to save time and money on meals and get more time to be social with my friends, as well as provide some original blog material. I have done a few potluck parties and always end up saving a huge amount of money with people pitching in on the food. So why on earth does a potluck dinner need to be a special occasion? I was thinking, depending on how close your are with your friends :) I could start having co-op dinners. Maybe start off with a couple times a month and see how things are going. Then you can easily do it as much or as little as you like. Another great way to save time and money is to do a freezer cooking get together. Where you can divide the cost of the food and supplies and make freezer meals together. You can invite as many friends as you want or can fit in your kitchen. Not only are you saving time, money, and sanity but you are having a fun time with a friend, doing something that is usually just a chore. I am one of those moms that doesn't have a very active social life, so trying to combine general daily deeds with my social activities seems to make sense. What do you think? Have you ever had a freezer cooking night with friends or family? Or regular potluck dinners?
