French Toast Casserole

My kids do this cool thing where we buy a snack at Costco.  They eat all of that snack from Costco.  They loved that snack from Costco. So naturally, when I'm at Costco again, I buy that snack at Costco.  Then the kids decide (without filling me in) that they hate that snack from Costco.  

Now we have exactly 40 of the snack that they will not eat.  All the while, they are complaining that we have no food.

Teenagers are the best.  Really, I love them, but the amount of snacks we have in the house while they tell me they're hungry and there is nothing to eat drives me mad.  

Anyway, I found a stash of chocolate chunk croissants that the kids used to love, just hanging out in a basket, rotting away and I had an idea.  French Toast Casserole anyone?!
