I may have to give this recipe a try, it's a challah that is 50% white flour and 50% whole wheat flour with no salt. The author did it in a mold rather than braiding it.
No Salt Challah
There's an inconsistency between the recipe and the instructions. 3 cups of flour is less than a pound but it talks about it being a 3 pound loaf. It looks like it is about 72% hydration, which is a bit on the moist side but otherwise the recipe appears to be in balance, though the dough weighs less than 27 ounces. It would not surprise me if I had to add a little flour to make it easy to roll out and braid.
