Step 1: Prepare the Teriyaki Sauce : In a small bowl, whisk together soy sauce, honey, brown sugar, rice vinegar, sesame oil, garlic, and ginger. Pour the sauce into a small saucepan and simmer over medium heat for about 3–4 minutes. Add the cornstarch-water mixture and stir until the sauce thickens slightly. Set aside.
Step 2: Cook the Salmon : Heat a non-stick skillet over medium-high heat and drizzle a little oil. Add the salmon cubes in a single layer. Cook for 2–3 minutes on each side until lightly browned and just cooked through. Pour the teriyaki sauce over the salmon and toss gently to coat evenly. Let it simmer for 1–2 minutes until the glaze clings beautifully to the fish.
Step 3: Make the Avocado Crema : In a blender or food processor, combine avocado, sour cream, lime juice, garlic, salt, and pepper. Blend until smooth and creamy. Adjust lime or salt to taste.
Step 4: Assemble the Tacos : Warm the tortillas in a skillet or microwave. Add a layer of shredded cabbage to each tortilla. Top with teriyaki-glazed salmon pieces. Drizzle generously with avocado crema. Sprinkle sesame seeds, green onions, and cilantro over the top. Serve with lime wedges for squeezing.
