Bento Chicken Teriyaki - cooking recipe

Ingredients

1 tablespoon soy sauce
1 tablespoon mirin
1 teaspoon sugar
4 ounces boneless chicken (breast, tenders, thighs, whatever you have)
1/2 tablespoon cooking oil
3 tablespoons water

Preparation

Mix first 3 ingredients together in bowl big enough to hold the chicken. Add the chicken. Let this marinate for 30 minutes, turning over halfway through.
Heat oil in a pan over medium heat.
Take the chicken out and pat dry. Reserve marinade. Put chicken skin side down (if you aren't using skinless) in pan and cook until browned on that side (just a minute or two) and then flip and brown the other side.
Pour reserved marinade over chicken and cover tightly. Lower heat and simmer until chicken is done, about 5 minutes.
Remove cover and raise heat back to medium high. Reduce marinade until it is more of a glaze. Toss chicken in glaze to cover.
NOTE: You could certainly substitute beef or tofu for the chicken in this recipe. Just adjust the cooking accordingly.
