Vegetables
- 1 ½ pounds portobello mushrooms, cut into thick ½-inch slices
- 1 small red onion, halved and cut into ½-inch-thick slices
- 1 red bell pepper, cut into ½-inch-thick strips
- 1 orange bell pepper, cut into ½-inch-thick strips

For Serving (Optional)
- 12 (6-inch) tortillas, warmed
- Salsa or hot sauce
- Guacamole
- Fresh cilantro leaves

Instructions
- Preheat the Oven: Set your oven to 450°F (232°C) and position the rack in the center to ensure even cooking.
- Prepare the Marinade: In a large bowl, mix together the taco seasoning, extra-virgin olive oil, and fresh lime juice to create a flavorful marinade.
- Marinate the Vegetables: Add the thickly sliced portobello mushrooms to the bowl and toss well, making sure each piece is evenly coated with the marinade.
- Arrange on Baking Sheet: Spread the marinated mushrooms, along with the sliced red onion and colorful bell pepper strips, evenly over a rimmed sheet pan to allow for roasting.
- Bake the Fajitas: Place the sheet pan in the preheated oven and bake for 20 minutes to soften and roast the vegetables.
- Optional Broil for Char: If you prefer a smoky charred flavor, switch your oven to broil and cook the vegetables for an additional 3 minutes, keeping a close eye to avoid burning.
- Serve: Warm the tortillas and serve the roasted fajita vegetables alongside salsa, guacamole, fresh cilantro leaves, and lime wedges for a customizable and vibrant meal.
