In a medium-sized bowl, combine the sesame oil, garlic, honey, soy sauce, orange juice, ketchup, sesame seeds, ginger, salt, and pepper. Whisk until all ingredients are well incorporated. Set aside.
Prepare the Broccoli
Steam the broccoli using a steamer basket for 10-12 minutes until tender. If you do not have a steamer basket, cook the broccoli in a pot of boiling water for 4-5 minutes or until tender. Drain and set aside.
Cook the Chicken
Heat 2 tablespoons of sesame oil in a large skillet over medium-high heat.
Season the chicken with salt, pepper, and cornstarch, tossing to coat evenly.
Add the chicken to the skillet and cook for 5-7 minutes, or until golden brown and fully cooked through.
Pour half of the prepared sauce over the chicken and cook for 6-7 minutes. Add the remaining sauce and cook for an additional 3-4 minutes. Remove from heat.
Stir in the steamed broccoli gently until well combined.
Adjust seasoning with additional salt and pepper if needed.
Garnish with extra sesame seeds, a squeeze of fresh lemon juice, and chopped green onions before serving.
