Prepare the Cabbage: Finely shred the green cabbage using a sharp knife or a food processor. Set aside.
Cook the Cabbage: In a large skillet or wok, heat half of the butter (1.5 tablespoons) over medium-high heat. Add the shredded cabbage and stir-fry for 5-7 minutes, or until it begins to soften but still retains some crunch. Avoid browning the cabbage excessively.
Season Cabbage and Set Aside: Season the cabbage with a portion of the salt (e.g., ¼ teaspoon), a portion of the black pepper, and the 2 teaspoons of white wine vinegar. Continue to stir-fry for an additional 1-2 minutes to combine the flavors. Transfer the seasoned cabbage to a separate bowl and set aside.
Sauté Aromatics: Return the skillet to medium-high heat and add the remaining half of the butter (1.5 tablespoons). Once the butter is melted, add the minced garlic, ¾ teaspoon of chili flakes, and 1.5 tablespoons of fresh ginger. Sauté for 1-2 minutes until fragrant, being careful not to burn the garlic.
Brown the Meat: Introduce the 15 oz of ground beef to the skillet. Cook, breaking it apart with a spoon, for 6-8 minutes, until thoroughly browned and cooked through. Most of the liquid should have evaporated. If necessary, drain any excess fat. If necessary, reduce the heat slightly to prevent sticking.
Combine and Finish Stir-Fry: Stir in the 1 teaspoon of low-sodium tamari. Return the cooked cabbage to the skillet along with the chopped scallions. Toss everything together and cook for another 2-3 minutes, until the scallions are slightly wilted and the entire mixture is heated through. Add the remaining salt and pepper, or adjust all seasonings to your taste. Just before serving, drizzle with 2 teaspoons of sesame oil.
Prepare the Spicy Wasabi Aioli: While the stir-fry finishes, prepare the aioli. In a small bowl, whisk together the ¾ cup of mayonnaise and 1 teaspoon of wasabi paste until smooth. For a milder flavor, you can start with ½ teaspoon of wasabi and add more until it reaches your desired level of spiciness.
Serve: Divide the Speedy Ginger Beef & Cabbage Sizzle among 3 bowls. Top each serving with a generous dollop of the Spicy Wasabi Aioli and sprinkle with toasted sesame seeds, if using. Serve immediately and enjoy!
