Today I downloaded the Kindle version of Real Food, Real Frugal for free. Based on a quick scan of the table of contents it looks like it may have some useful information. Just be sure to check the price before downloading to make sure it’s still free.
For other free cooking related e-books check out The Prudent Pantry.
Also, you can still enjoy free Kindle books even if you don’t have a reader. You can get free downloads for your PC, Mac, or other devices here.
