She made a delicious breakfast muffin creation and sent me photos of which I changed her recipe to this breakfast casserole,  instead.   To my surprise, this spinach and egg breakfast casserole turned out to be equally delicious.

She sent me her recipe and while I am currently on a business trip in Europe with my husband and didn’t have a muffin pan, so I made it in a small casserole glass baking dish instead.

So glad she did!
