I know I preach a low fat lifestyle (hell, I author a fat-free blog!) and that is how I live and eat... but I'm not going to lie. I love avocados and I love guacamole. I figured, if beans can make brownies, there has to be a way to make lower fat guacamole, right? While this guacamole isn't fat-free (soybeans have fat in them) its still low fat and also high in protein. You could try substituting peas for the soybeans for a truly fat-free version.
