I've been reading and looking at the success stories from page 1 and after an hour am on page 85. I am excited to do this! But I am confused about what the title says... What exactly is the extra 5% grains? Legumes? Or am I just not getting it??

I'm also not super rich, and I have almost no confidence that this endeavor will last because I don't know different CHEAP/AFFORDABLE recipes to make and stock up on for the week... Any advice would be GREATLY appreciated.
