If you don't have a crock-pot yet, you should go ahead and invest in one. A crock-pot is so easy to cook with, and the recipes will come out so delicious, it won't be long before you are addicted to cooking with it!
A crock-pot in the kitchen will save you money and time. You can put all the ingredients for your meal in the crock-pot in the morning, let it slowly cook throughout the day, and you will have a delicious meal ready at dinner time. And one of the greatest things about using a crock pot is that you can use less expensive cuts of meat--it will still be delicious and tender because it slow cooks all day long.
Another benefit of the Crock-pot -- the energy usage is much smaller when compared to using your oven! You will find countless recipes for your crock-pot that are healthy, delicious and will save you money at the grocery store. Just check the Internet for recipes, or check out some cookbooks at your library.
One last thought. If you get a crock-pot meal started early in the morning, it doesn't matter how hectic and crazy your day may get when it comes to dinner because you will still have a great meal ready for everyone--no need for a pizza or other fast food to feed the kids when mom is exhausted at the end of the day!
