Step-by-Step Cooking Instructions

Step 1: Prep the Mushrooms & Veggies

1. Wipe the portobello mushrooms clean with a damp paper towel and remove the stems.
2. Slice them into thick strips, similar to the size of traditional fajita meat.
3. Thinly slice the bell peppers and red onion.
4. Mince the garlic and set everything aside.

Step 2: Marinate for Maximum Flavor

1. In a large bowl, whisk together the olive oil, lime juice, cumin, smoked paprika, chili powder, oregano, salt, and pepper.
2. Add the sliced mushrooms, bell peppers, and onions. Toss everything well to coat.
3. Let it sit for 10-15 minutes while you prepare the toppings.

Step 3: Sauté to Perfection

1. Heat a large skillet or cast-iron pan over medium-high heat.
2. Add the marinated vegetables and cook for 8-10 minutes, stirring occasionally. The mushrooms should be tender, and the peppers slightly charred.
3. Once cooked, remove from heat.

Step 4: Warm the Tortillas

1. While the veggies are cooking, heat a dry pan over medium heat.
2. Warm each tortilla for about 30 seconds per side until soft and pliable.

Step 5: Assemble & Serve

1. Divide the mushroom and vegetable mixture evenly among the tortillas.
2. Add your favorite toppings like avocado, fresh cilantro, jalapeños, salsa, or vegan sour cream.
3. Squeeze a little extra lime juice on top and enjoy!
