That could be very interesting! I don't think I could completely give up bread..
The one trigger bread that I DO NOT ALLOW MYSELF TO BUY is good rye bread (the kosher NYC style, with seeds). I just don't buy it because I eat the whole loaf.
I also don't buy crusty Italian bread for the same reason. That said, when I go out for breakfast, I always get rye toast. That is what I limit myself to.
I'm trying to think if there is something else I could give up for a month... hmm..
You gals have fun! Keep it updated, I'd love to see your progress!!
