Honestly, I just eat the challah. I make sure after the shabbat service when we are given some challah, I take the smallest piece I can find and take a bite. I figure that the one bite of challah every other week (I don't go weekly... I'm a bad Jew!) isn't going to de-rail my progress or harm my gut too much!
I may give this recipe a try for Rosh Hashannah though; I'll have to buy that challah mold mentioned in the post you linked to, as the braided look is pretty much necessary! (It will be sad, though, knowing I can't braid it... sigh...)
