To create this delicious Beef & Veggie Mix, simply follow these easy steps:

1. Prepare the Vegetables: Wash and chop your vegetables into bite-sized pieces for even cooking. Set aside.
2. Cook the Beef: In a large skillet or wok, heat the olive oil over medium-high heat. Add the ground beef and cook until browned, breaking it up into smaller pieces.
3. Add Onions and Garlic: Once the beef is browned, add the chopped onion and minced garlic. Sauté for 2-3 minutes until fragrant and onions are translucent.
4. Stir in Vegetables: Add the mixed vegetables to the skillet. Stir well and cook for another 5-7 minutes until vegetables become tender-crisp.
5. Season the Mix: Pour in the soy sauce, oyster sauce (if using), salt, and black pepper. Stir to combine all flavors.
6. Thicken Sauce: If you’d like a thicker sauce, add the cornstarch mixture to the skillet. Stir continuously until the sauce thickens, about 1-2 minutes.
7. Final Stir and Serve: Once everything is well-mixed and cooked through, remove the skillet from the heat. Serve over cooked rice or noodles.
