Steps
1. In a skillet, melt the butter over medium heat.
2. Add the diced chicken breast and season with salt and pepper. Cook until the chicken is browned and cooked through, about 5-7 minutes.
3. In a small bowl, whisk the egg and add it to the skillet with the chicken.
4. Stir the egg gently into the chicken, allowing it to scramble and cook through, about 2-3 minutes.
5. Add the margarine and mix until melted and creamy. Adjust seasoning if needed.
6. Serve hot, garnished with chopped parsley if desired.
