The stockings are hung by the chimney with care, brightly wrapped packages peak out from under the tree, and bleary-eyed little ones begin to stir in their beds. The smell of coffee and cinnamon mingles with the aroma of a fresh-from-the-oven Greek Breakfast Casserole. One thing is for certain, the holidays have arrived!

Growing up, Christmas meant freshly baked cinnamon buns and savory breakfast casserole enjoyed while lounging around the living room exchanging gifts. That first holiday on a gluten-free diet was like torture. Watching everyone else enjoy our holiday favorites and being confined to a bowl of melon balls was not exactly the “Merry Christmas” we were used to. Thank goodness for Udi’s! Now, everyone can enjoy delicious, piping hot gluten-free cinnamon rolls and egg casseroles without feeling deprived or left out of the holiday merriment.

This recipe for Greek Breakfast Casserole is one of our favorites! Salty feta cheese and savory sundried tomatoes nestled among toasted cubes of Udi’s White Sandwich Bread create a hearty breakfast classic perfect for the holidays. Prepare the casserole the night before you plan on serving it for a quick, pop-in-the-oven gourmet meal that is sure to make your holiday be-UDI-ful and bright!
