In a large skillet over medium-high heat, add the olive oil and add about half of the chicken. Season with salt, pepper, garlic powder, and ground ginger as desired. Cook 3-4 minutes on each side until the pieces are golden brown. Remove and set in a covered dish. Repeat with the remaining chicken.
1 lb boneless skinless chicken breasts, garlic powder, ground ginger, kosher salt, black pepper, 2 tablespoons vegetable oil
While the chicken cooks,combine the ingredients for the sauce in a small bowl. Taste and adjust the seasoning as desired. Set aside.
1/4 cup hoisin sauce, 3 tablespoons brown sugar, 2 tablespoons toasted sesame oil, 2 tablespoons soy sauce, 1½ teaspoons ground ginger, 2 teaspoons fresh garlic, 2 tablespoons rice wine vinegar, pinch red pepper flake
Then, add another tablespoon of oil and add the broccoli and mushrooms. Cook about 4 minutes until the vegetables are slightly tender.
2 cups broccoli florets, 1 cup mushrooms, 2 tablespoons vegetable oil
Add the remaining tablespoon of fresh garlic and cook 1-2 minutes until fragrant.
1 tablespoon fresh garlic
Reduce the heat to medium and return the cooked chicken to the frying pan and add the prepared sauce. Cook for 2-3 minutes more, stirring frequently so that sauce warms and coats all the chicken and vegetables.
