Croissant Breakfast Casserole ****

I have made this one nearly every Christmas morning since the first time I tried it back in 2007.  That's how much we love it.  It's become a tradition for us.  I do always change it up with the additions that I've noted, but that's mainly because I want to make it stretch further.  It's still basically the same as the original recipe (except for the added sausage and green pepper), so I keep it under Dottie's name.  She's the brilliant mind behind this one.  Our Christmas mornings wouldn't be the same without it!  Oh, and the last few times around, I've used Egg Beaters instead of eggs, since I almost always have some that need to be used up.  No difference at all, other than having to cook it for the full 60 minutes.  But the taste is still wonderful!  Just as proof of how great it is, I've been making it for 9 years now, and we're still every bit as excited to dig into it as we were the first time. :-)

CROISSANT BREAKFAST CASSEROLE
This is a no fail recipe! Easy for the beginner cook, and looks very elegant. Can be doubled and tripled with no problem! Cook time does not take into consideration overnight sitting time, so plan ahead!!
