Instructions
Cook the Rice
Cook rice according to package directions so it's ready when the stir-fry is finished.
Velvet the Beef
In a medium bowl, whisk together soy sauce, rice vinegar, cornstarch and baking soda; add sliced beef and toss well to coat. Set aside.
In another medium bowl, whisk together soy sauce, water, chili paste, honey, rice vinegar, crushed Sichuan peppercorns and cornstarch until well combined. Set aside.
3 tablespoons soy sauce, 1/4 cup water, 1 tablespoon rice vinegar, 1 tablespoon hot chili paste, 1 tablespoon honey, 1 teaspoon Sichuan peppercorns, 1 teaspoon cornstarch
Sear the Beef
Heat 2 tablespoons of the avocado oil in a large skillet over high heat until nearly smoking. Add beef in a single layer and sear, 1 1/2 to 2 minutes per side. Reduce heat to medium and transfer beef to a clean plate.
Stir-Fry
To same skillet, add remaining 1 tablespoon of avocado oil. Add garlic and ginger; cook and stir until fragrant, about 30 seconds. Add bell pepper and green onions; cook and stir 2-3 minutes until just tender.
3 cloves garlic, 2 tablespoons minced peeled fresh ginger, 1 red bell pepper, 6 green onions
Combine and Serve
Return beef and any accumulated juices to skillet. Stir soy sauce mixture (cornstarch will have sunk to the bottom) and add to skillet, scraping up any browned bits; bring to a boil. Reduce heat and simmer, stirring constantly until sauce is thickened and bubbly, 1-2 minutes.
1/2 cup roasted unsalted peanuts, red pepper flakes
Transfer to serving platter or divide among 4 bowls. Sprinkle with peanuts and red pepper flakes (optional); serve with hot cooked rice.

Notes
Slicing the Steak: For the easiest, thinnest slices, pop the flank steak in the freezer for 15-20 minutes before slicing. It makes a world of difference.
Sichuan Peppercorns: For the best flavor, I recommend buying whole Sichuan peppercorns and grinding them yourself in a spice grinder or with a mortar and pestle.
Heat Level: This dish has a nice warmth to it, but it's not overwhelmingly spicy. If you love heat, feel free to add a few whole dried red chilis to the oil along with the garlic and ginger.
