I am a fan of the slow cooker. I think that it is a mom's best friend - whether you are a working mom or a SAHM. I have found a new recipe site solely dedicated to the slow cooker http://www.slowandsimple.com/ This site is for ONLY slow cooker recipes, and I am adding it to my recipe links list.
The benefits of a slow cooker are many including 'hands off' cooking which is good if you work outside of the home. When I worked during the day, I loved the thought of coming home and not having to worry about my dinner - because it was waiting for me, all I had to do was a side dish, usually a salad that takes about 5 minutes to prepare, and I was done.
The library has a ton of cookbooks (especially if you search the regional system and have it shipped to your local branch), so you don't have to purchase one, you can just borrow it as often as you wish and as many different ones as you wish.
Other slow cooking benefits:
1) reduces need for take out
2) maintains nutrients even if your picky eaters 'pick out' the veggies (since they are cooked together)
3) uses much less energy than the oven and stove
4) no pre-cooking required
5) one pot to clean
6) slow cooker meals are usually less expensive
7) food stays hot for serving after you turn it off so you don't have to nuke your dinner
Today is rainy and windy (thanks Hanna), so I am cooking a slow cooker chicken creole.
