I have mentioned these books before but they are still available if you missed it last time.
You can download free cookbooks from Gooseberry Patch– like Mac and Cheese Recipes, Crock Pot Recipes, 25 Chocolate Chip cookie recipes and more.
You just need to download the Amazon software and then you can read the cookbooks on your PC, smart phone, Kindle, or iPad.
If you are looking for some other cookbooks to spice things up a little, I was thinking these books looked interesting (sadly they are not free):
Food Network Magazine: 250 Fun and Easy Recipes $13
Our Best Bites: Mormon Moms in the Kitchen $16.19
Grilled Cheese Please: 50 Scrumpticiously Cheesy Recipes $9.73

Thanks for the heads up on this. I downloaded several on my kindle.
