White Flour - why must you be SO good??

I took the kids to the park today and on the way home I was exhausted and didn't feel like making them lunch.  I try very hard not to bring them to McDonald's so I went to a local bread company to pick them up some of the pizza they make there.  They didn't have pizza but they had rolls that had just come out of the oven.......Anyway, this is a lot of rambling before getting to the point of this post which is this:  I had a roll with tuna and. it. was. AWESOME!  I realize that one white flour roll isn't the end of the world, but it's certainly NOT on the diet I'm following.  But did I mention how awesome it was?  :-)  Well, I'm back on track now, back to following my "yeast eliminating diet", and back to fighting fat.
