Preheat oven to 220°C (425°F). Line a sheet pan with parchment paper.
In a large bowl, combine olive oil, lime juice, garlic, chili powder, cumin, paprika, salt, and pepper.
Toss the plant-based shrimp, bell peppers, and onions in the marinade until evenly coated.
Spread everything out on the sheet pan in a single layer.
Roast for 18–20 minutes, stirring once halfway through.
Warm the tortillas while your fajitas roast — multitasking counts as fitness.
Once the veggies are tender and caramelized, remove from the oven.
Fill tortillas with roasted goodness and drizzle with vegan sour cream.
Sprinkle cilantro and squeeze fresh lime juice on top.
Serve hot, enjoy, and bask in the applause (even if it’s just your own).
