Step 1: Prepare the Sauce - In a bowl, whisk together the tamari or soy sauce, water, brown sugar, hoisin sauce, toasted sesame oil, black pepper, and cornstarch. Mix until the cornstarch is fully dissolved and set this sauce aside.
Step 2: Marinate the Beef - If you have time, marinate the beef strips in a small amount of the sauce for about 15-30 minutes. This will enhance the flavor and tenderness of the beef.
Step 3: Heat the Pan - Heat your wok or large skillet over medium-high heat and add the avocado oil. Ensure the oil is hot before you add the beef.
Step 4: Cook the Beef - Add the marinated beef strips to the pan in a single layer. Sear the beef for about 2-3 minutes on each side until browned but not fully cooked. Remove the beef from the pan and set aside.
Step 5: Sauté the Aromatics - In the same pan, add the minced ginger and garlic. Sauté for about 30 seconds until fragrant, but be careful not to burn them.
Step 6: Add the Vegetables - Toss in the sliced carrots, snow peas, and mushrooms. Stir-fry the vegetables for 3-4 minutes until they are tender yet still crisp.
Step 7: Combine Everything - Return the beef to the pan. Pour the sauce over the beef and vegetables. Stir well to combine, ensuring that everything is coated with the sauce. Cook for an additional 2-3 minutes until the sauce thickens and the beef is cooked through.
Step 8: Add Bean Sprouts - Finally, add the bean sprouts (or your vegetable of choice) and stir for another minute until they are slightly wilted but still crunchy.
