Heat olive oil in a large pan over medium heat, add in the chicken and sprinkle with salt. Cook chicken for 2-3 minutes per side or until cooked through. Transfer to a bowl and set aside.
Reduce heat to low, add in the ginger and garlic, cook for 1 minute or until fragrant. Add in the tamari or soy sauce, lemon juice, sesame oil, and honey, mix together.
In a separate bowl, whisk together the cornstarch and water until the cornstarch has dissolved. Transfer corn starch and water to the sauce along with the cooked chicken.
Stir until sauce thickens, about 3-4 minutes. Divide between four bowls with rice and broccoli, then top with sliced green onions and sesame seeds.
Notes
Storage: Store the rice and vegetables in a separate container than the teriyaki chicken. Place them both in airtight containers in the fridge for up to 3 days.
