Creating your shrimp stir fry can be simple and enjoyable if you follow these straightforward steps:

1. Prep Ingredients: Gather all your ingredients and chop the vegetables into bite-sized pieces. Have the shrimp ready to go.
2. Heat Oil: In a large skillet or wok, heat 2 tablespoons of vegetable oil over medium-high heat.
3. Cook Shrimp: Add the shrimp to the skillet and cook for about 2-3 minutes until they turn pink and opaque. Remove shrimp and set aside.
4. Add Aromatics: In the same skillet, add minced garlic and ginger, stirring for about 30 seconds until fragrant.
5. Stir in Vegetables: Add the mixed vegetables to the skillet and stir-fry for about 3-5 minutes until they are tender but still crisp.
6. Combine Sauces: In a small bowl, mix soy sauce, oyster sauce, and cornstarch slurry. Pour this mixture into the skillet, stirring continuously to coat the vegetables.
7. Return Shrimp: Add the cooked shrimp back to the skillet and toss everything together for an additional 1-2 minutes until heated through.
8. Season: Drizzle with sesame oil and add red pepper flakes if using. Season with salt and pepper to taste.
9. Serve: Remove from heat and serve hot over cooked rice or noodles. Garnish with sliced green onions.

These simple steps will guide you to create a shrimp stir fry that is not only delicious but also visually appealing.
