Thinly slice the skirt steak into bite-sized pieces and heat 2 tablespoons of sesame oil in a non-stick pan. Sauté the steak fillets over high heat for 1-2 minutes on each side. Mince and add the garlic. Add the soy sauce, Erythritol, and sesame seeds, and stir to create a thick glaze.
In a small mixing bowl, whisk together 4 tablespoons of sesame oil, lime juice, Erythritol, chili flakes, and minced garlic to make the dressing.
Toss the greens in a salad bowl and add the chopped avocado. Top with the steak fillets and drizzle with the dressing. Serve at room temperature.
