Preheat the Oven: Set it to 400°F (200°C) because roasted perfection requires a little heat and patience.
Marinate the “Chicken”: Toss seitan or tofu with olive oil, garlic powder, paprika, thyme, salt, and pepper. Let it rest for 10 minutes.
Prep the Veggies: In a bowl, combine sweet potatoes, onion, and bell pepper with olive oil, rosemary, smoked paprika, and lemon juice.
Assemble the Pan: Spread veggies evenly on the baking sheet. Nestle the marinated “chicken” pieces on top like they own the place.
Roast: Bake for 20 minutes. Flip everything, then roast another 15 minutes until golden and caramelized.
Serve & Shine: Garnish with parsley and a squeeze of lemon. Serve hot and accept compliments gracefully.
