The options for ingredients for this dish are virtually endless. For mine, I used bacon, cheddar, mushrooms, and green bell peppers.
I got my oven-safe mug at Publix. I love it because it also came with a lid (not oven-safe) that makes it perfect to carry to work. I greased the mug and scrambled two eggs directly in it. To the eggs, I stirred in my meat, cheese, and veggies. I used a lot of veggies in this the egg pretty much acted like a glue to hold them together.
I baked the mixture at 375 for 25 minutes. It came out fluffy and light.
To reheat it for lunch today, I put it in the microwave for one minute. It was so easy and fast and the students didn't have to wait on me for my lunch to cook.
