A Korean lunchbox packed with chicken, rice, and colorful banchan is a high protein lunch that makes everyone in the break room jealous.
Slice the chicken breast into thin strips and marinate in a mix of soy sauce, minced garlic, sugar, and ground black pepper for at least 15 minutes while preparing the vegetables.
Peel and julienne the carrot and zucchini. Heat 1 tsp sesame oil in a skillet over medium-high heat and stir-fry the carrot for 2-3 minutes until just tender; remove and set aside. Repeat with zucchini, adjusting the heat to prevent browning.
Beat eggs with a pinch of salt and cook a thin egg omelet over low heat in a nonstick pan; once set, slice it into thin strips and reserve.
Increased heat to medium-high, add marinated chicken to the skillet, and cook for 4-6 minutes, stirring frequently until the chicken turns golden brown and is cooked through. Add sesame oil at the end for aroma.
To assemble the dosirak, portion cooked white rice into each box, topping with sautéed chicken, vegetables, sliced egg, and a strip of nori. Sprinkle sesame seeds over the chicken and serve warm or at room temperature.
