In a medium bowl, combine the orange juice, diced chipotle pepper, adobo sauce, minced garlic, ground cumin, dried oregano, and a pinch of kosher salt. Stir until well mixed.
Add the shredded oyster mushrooms to the marinade, making sure they are fully coated. Allow the mushrooms to marinate for at least 15 minutes.
Place a large skillet over medium heat and add 2 tablespoons of avocado oil. Once the oil is heated, add the marinated mushrooms to the skillet, spreading them out evenly.
Cook the mushrooms for about 10-15 minutes, stirring occasionally, until they are tender and slightly caramelized. Taste and adjust seasoning if necessary.
In a separate pan, warm your corn tortillas over medium heat for about 30 seconds on each side, or until they are pliable and slightly toasted.
Once the mushrooms are cooked and the tortillas are warmed, place a generous serving of the sautéed oyster mushrooms on each tortilla. Top with your choice of dairy-free cheese, diced white onion, fresh cilantro, sliced avocado, salsa, and hot sauce.
Serve your delicious Oyster Mushroom Tacos immediately while they are warm, and enjoy the burst of flavors in every bite!
