Jo,
This sounds so delicious...I'm definitely gonna try this....I always make a "breakfast type" casserole but never tried anything like this...I know this will be loved by my Italian family!!!
Wasn't it sweet of Kathy to find a recipe with Zwieback??? I tried to search the web, but couldn't find one the other day...I hope its Vivian treasured memory from her mom....anyway, we've all benefitted too!!!
