Heat a large skillet over medium-high heat with enough oil to coat the bottom. Once hot, add the eggs (whole or whites only—your choice) and scramble. Since all other ingredients are already cooked (hence the leftover part), add them one by one, stirring as you go. Once the cabbage begins to wilt, add soy sauce and salt. The total cooking time should be about 15 minutes.
Notes
The carrot for this dish is not precooked. In order for it to soften at the same time it takes the rest of the meal to cook; I chop them very small. They will be firm yet soft in your stir fry.
