Big hit delicious Egg Croissant Casserole!

I got this marvelous recipe from my Nephew, Adam who is a private chef in Breckenridge, CO.  Adam loves to cook but his new love is his 4 month old son River.  I have to tell you that River is appropriately named because Adam’s passion is fishing.  I haven’t met River in person yet, but  thanks to his Mom Cait, I’ve gotten lots of photos.  Looking forward to meeting him in August when I head to Colorado to celebrate my sister Carol’s 70th birthday.  Finally, I won’t be the only one in the family to hit the 70’s
