I have a few set pieces that are popular:
Mostly scrambled with:
Onions, smoked salmon (hey, this is the pacific NW), cream cheese, and dill.
Carmelized onions, green apples, goat cheese
Those first two are shamelessly lifted from the (now defunct) Titanic Cafe in San Francisco.
Roasted red peppers, sun dried tomatoes, red onions, mozarella, spoonful of spaghetti sauce
Pesto, artichoke hearts, feta, tomatoes
Italian sausage, mushrooms, onions, peppers.
Whatever else I can find in the fridge.
Dad's barbecue'd eggs - basically poached eggs in the steamer egg cup things, but you pour in a little dollop of Hickory BBQ sauce as soon as an outer skin forms aginst the cup. The sauce will get sealed into a little chamber by the yolk when the white solidifies. Smokey and good on toast.
