Cut the chicken into bite-size pieces. Cook it in a very large skillet or wok with about half the olive oil until browned and cooked through, about 6-8 minutes. Remove and set aside.
Add the frozen vegetable blend to the skillet.
Cook uncovered over high heat for 8-10 minutes, stirring occasionally, so the excess water evaporates rather than steaming the vegetables. Avoid crowding into a deep pot.
Add the garlic, ginger, and crushed red pepper. Cook for 30-60 seconds, stirring constantly.
Return the chicken to the skillet.
Add the soy sauce and rice vinegar. Toss for 1-2 minutes over high heat.
Adjust seasoning with black pepper and serve.
