Heat olive oil in a pan and sauté the onion.
When the onion becomes translucent, add the chicken breast and cook thoroughly.
Add soy sauce, stevia, cooking wine, and water, then bring to a boil.
Beat the eggs well and pour into the pan, cooking gently over low heat until softly set.
Place the cooked ingredients over rice and sprinkle with chopped green onions.
