Begin by trimming the ends of the oyster mushrooms and shredding them into bite-sized pieces. This will help them cook evenly and absorb the flavors of the marinade.
In a bowl, combine the shredded oyster mushrooms with the orange juice, chipotle pepper, adobo sauce, minced garlic, cumin, oregano, and a pinch of kosher salt. Mix well to ensure all the mushrooms are coated. Let the mixture marinate for about 10 minutes.
In a large skillet, heat 2 tablespoons of avocado oil over medium heat. Once the oil is hot, add the marinated mushrooms, including all the juices from the bowl. Sauté the mushrooms for about 8-10 minutes, stirring occasionally, until they’re tender and slightly caramelized.
While the mushrooms are cooking, warm the corn tortillas in a separate skillet or tortilla warmer over low heat.
Once the mushrooms are cooked and the tortillas are warm, place a generous portion of the sautéed oyster mushrooms onto each tortilla.
Top your tacos with your favorite toppings, such as dairy-free cheese, diced white onion, fresh cilantro, slices of avocado, salsa, and hot sauce.
