Beat 2 eggs with a pinch of salt and pepper.
Thinly slice the onion and shred the chicken breast into small pieces.
Sauce: Mix 1 tablespoon each of soy sauce, mirin, allulose (or stevia), and oyster sauce, plus 2 tablespoons of water.
Prepare by placing the scrambled eggs on top of the rice, then stir-fry the chicken breast.
Once the chicken absorbs the oil, add the onions and sauté until they're halfway cooked, then pour in the prepared sauce and simmer on low heat.
Place the chicken and onion mixture over the rice, then top with seaweed flakes, mayonnaise, and sesame seeds.
