Cook the rice: You can choose your favorite type of rice. I chose sushi rice, as I love how well it goes with the teriyaki chicken. Just make sure you use the right amount of water for the type of rice you choose so that you don’t end up with overcooked rice. For the sushi rice, I use 1.2 cups of water for 1 cup of rice, let it simmer for 15 minutes and then let it sit.
Steam the broccoli: You can steam the broccoli using your preferred method. I usually boil water in a pot, add the broccoli, turn down the heat and let it steam with the pot covered. After 5 minutes I usually drain the water. This way I have broccoli that has softened, but is still crisp.
Prepare homemade teriyaki sauce: Simply add all of the ingredients to a bowl, mix everything and set the sauce aside.
Make the teriyaki chicken: Now you can prepare the star of this dish! Simply sear the chicken from both sides, take it out of the pan and set it aside, add the homemade teriyaki sauce to the pan and let it simmer until it thickens up. If it doesn't get thick enough, add some of the cornstarch slurry until the sauce has the desired consistency. Now add back the chicken and cover it with the sauce.
