Toast bread and cut into cubes. Set aside.
Spray a large microwave-safe mug lightly with nonstick spray. Add bread cubes, egg substitute, cheese wedge pieces, and ham, and stir. Microwave for about a minute. Stir gently, and then top with shredded cheese. Microwave for another 30 to 45 seconds, until scramble is just set. Stir and enjoy!
