Marigrace, I agree that supermarket bread is a lot "less dense" than homemade. That is where the extra calories are coming in I'll bet. It definitely sounds delicious though!
Nelie, Thank you for the advice on keeping it refridgerated after thawing. Unfortunately, we do not have a Trader Joe's in Central Florida. There are about four health food stores near me, so I will call for prices on the bread before I decide which store to drag myself too, lol. I usually just go to the closest, but if it is a huge difference I'll drive farther.
