In a bowl, whisk soy sauce, maple syrup, rice vinegar, garlic, ginger, sesame oil, lemon juice, and cornstarch slurry.
Heat olive oil in a pan over medium heat. Add vegan salmon and cook for 2–3 minutes on each side until golden.
Pour the glaze mixture into the pan and let it simmer.
Cook for 5–7 minutes, spooning the sauce over the fillets until thick and glossy.
Once coated evenly, remove from heat and let the sauce cling beautifully to each piece.
Garnish with sesame seeds and green onions for that restaurant-level finish.
Serve with rice, noodles, or roasted veggies — basically whatever helps soak up that sauce.
Take a deep breath, admire your masterpiece, and prepare for applause (from yourself, obviously).
