Heat 1 tbsp olive oil in a large skillet or wok over medium-high heat.
Add chicken cubes and cook until browned, about 5-7 minutes. Remove and set aside.
In the same pan, add ginger, garlic, and vegetables; stir-fry for 3-4 minutes until tender-crisp.
Mix soy sauce, honey, chicken broth, red pepper flakes, and cornstarch slurry; pour over vegetables and chicken. Cook until sauce thickens, about 2-3 minutes.
Drizzle with toasted sesame oil, toss to combine, and serve hot.
Notes
For extra flavor, garnish with chopped green onions or sesame seeds.
