I used a MT tuna can, that I removed BOTH ends, and buttered the inside, put into a small fry pan, cracked the egg into it & slowly fried it, THEN removed the can, turned the egg over and cooked the other side. It fits right on the muffin, add the other choices and micro for 20 seconds to heat!!
PS: You can put it in a baggie and makes a quick "heat up" at school OR coffee break at work!!
