Start by rinsing your fresh green beans under cold water. Trim the ends and cut them into halves or thirds, depending on your preference for bite-sized pieces.
In a small bowl, whisk together the soy sauce, rice vinegar, sweetener, red pepper flakes, and white pepper. Adjust the amount of red pepper flakes based on your desired spice level.
In a large skillet or wok, heat the vegetable oil over medium-high heat until shimmering.
Add the minced garlic and ginger to the hot oil. Sauté for about 30 seconds, or until fragrant, being careful not to burn them.
Add the prepared green beans to the skillet. Stir-fry for about 5-7 minutes, until they are bright green and tender-crisp.
Pour the sauce over the green beans and stir to coat evenly. Cook for an additional 2-3 minutes, allowing the flavors to meld and the green beans to absorb the sauce.
Transfer the Spicy Szechuan Green Beans to a serving dish. Enjoy them immediately as a side dish or over a bed of rice for a delightful main course.
