Spray the inside of a microwave-safe mug with cooking spray, or use a small amount of butter or oil.
Place chopped spinach, chopped chives, and chopped scallion in the mug, and microwave for one minute.
Drop in the eggs, do not stir. Microwave for 45 second to one minute – until barely set around the edges. This may vary a bit depending on the strength of the microwave.
Remove and add cheese, salt, and pepper. Stir together.
Place back in microwave and cook for an additional 10-30 seconds. This will vary depending on the amounts used. Remove from microwave before it is quite “set” as it will continue to cook in the hot mug.
Eat from the mug, or turn out onto a plate.
