After we have burgers for ourselves or for a crowd, there inevitably are leftover sliced onions, tomatoes and cheese. We used spinach dip as a spread/dip as well this time. A easy way for me to use these up before they disappear into the depths of the fridge is the next morning in scrambled eggs the next morning.
Sauté in melted butter or coconut oil, and then add your slightly beaten eggs and scramble as usual.
They'd also work well in quiche, it's surprising how well eggs adapt to different additions isn't it?
