I love making my own bread! I don't follow SB, so I'm not sure what ingredients you can and can't have. Google SB and bread recipes and I bet you will find a bunch.
My breadmaker is one of my favorite appliances because it allows me to choose what I add to my bread. We make our own soy milk, so the okara (soy sludge) is a great protein additive which also gives the bread a nice, moist texture.
If you don't have a breadmaker, all that kneading is great exercise too! The only caution I have has already been stated - warm, fresh bread is sooooo inviting. It is hard to stop after one slice
