Preheat the Oven: Set it to 400°F (200°C). Prepare your baking tray like a pro—parchment paper is your best friend.
Marinate the “Chicken”: Combine olive oil, lemon juice, garlic powder, oregano, thyme, salt, and pepper. Toss seitan or tofu and let it marinate 10 minutes.
Roast the Potatoes: Mix diced potatoes with oil, rosemary, lemon zest, and seasoning. Spread them evenly on the tray. Bake for 15 minutes.
Add the “Thighs”: Place the marinated vegan protein on the same tray. Bake for another 20 minutes until everything looks gorgeously golden.
Prepare Marinade: Whisk lemon juice, soy sauce, maple syrup, mustard, garlic, and parsley.
Finish & Serve: Drizzle the lemon herb mixture over baked pieces and toss lightly for that tangy shine. Serve hot and feel like a culinary goddess.
