I make egg cups (egg muffins). I beat as many eggs as I need and add chopped spinach and sometimes a good feta cheese. You can add whatever you want. Chopped tomatoes and ground sausage would be good. Pour into a silicone muffin pan and bake on 375 until they are super puffy looking. I have tried a greased metal muffin pan and they do not come out well no matter how well I grease it so I resorted to the silicone which works great.
I make these at the beginning of the week and keep them in the fridge. My husband pops one in the microwave each morning.
