Creating the Heavy-on-the-Veggies Beef and Vegetable Stir Fry is straightforward when you follow these simple steps:

1. Prep the Vegetables: Wash and slice all the vegetables as indicated in the ingredients.
2. Marinate the Beef: In a bowl, combine sliced flank steak with 1 tablespoon of soy sauce and cornstarch. Mix well and let it marinate for 10 minutes.
3. Heat the Pan: In a large skillet or wok, heat 1 tablespoon of vegetable oil over medium-high heat.
4. Cook the Beef: Add the marinated beef to the hot skillet, cooking until browned (about 3-4 minutes). Remove and set aside.
5. Add More Oil: In the same skillet, add the remaining 1 tablespoon of oil.
6. Stir-fry Vegetables: Add minced garlic and ginger, sautéing for 30 seconds before adding broccoli, bell pepper, carrot, and snap peas. Stir-fry for about 5-7 minutes until the vegetables are tender-crisp.
7. Combine Beef and Sauce: Return the cooked beef to the pan. Add the remaining soy sauce and oyster sauce, stirring together. Cook for another 2-3 minutes.
8. Taste and Adjust: Season with salt and pepper as desired.
9. Serve Hot: Serve immediately over cooked rice or noodles for a complete meal.

These steps will guide you through creating an incredible beef and vegetable stir fry filled with flavor and nutrition.
