Heat the vegetable oil in a large skillet or wok over medium-high heat.
Add minced garlic and ginger, sautéing for about 30 seconds.
Add the sliced chicken breast and cook until browned and cooked through.
Stir in the mixed vegetables and cook for 3-4 minutes until tender-crisp.
Pour in the soy sauce and oyster sauce, mixing well.
Season with salt and pepper to taste.
Stir fry for another minute until everything is heated through.
Remove from heat and serve over cooked rice or noodles.
Garnish with fresh herbs if desired.
