It's Christmas, and coffee cake is your tradition. Years from now they'll treasure their memories of Mom's coffee cake.
Fry up some sausages to go with. It's just one thing, it won't be that much trouble.
For other mornings of the year, these muffin-tin mini-quiches are good. Just don't call them quiche. Call them egg & cheese muffins.

(The recipe says sausage and mushroom, but you can vary the ingredients. I like ham, scallion and onion.)
