Step 1: In a medium-sized bowl, mix together oil, 1 1/2 teaspoons salt, chili powder, garlic powder, cumin, and tablespoon of lime juice.
DIRECTIONS:
Step 2: Put the mushrooms in a shallow glass baking dish in a single layer. Cover the mushrooms with the marinade, stirring them gently to coat as needed. Allow to sit at room temperature for half an hour.
Step 3: In the meantime, combine the cabbage, onion, 2 tablespoons of cilantro, and the remaining 2 tablespoons of lime juice in a medium-sized bowl. Add the remaining 1/2 teaspoon of salt to taste.
Step 4: Preheat a grill for five minutes on medium-high heat. Grates should be cleaned and oiled.
Step 5: Take the mushrooms out of the marinade and allow any extra to fall off. Sear in a single layer for one to two minutes on each side, or until deeply browned on both sides, rotating halfway through.
Step 6:Place two avocado slices and a generous portion of slaw in the middle of each tortilla. Add three to four grilled portobello slices, some cilantro, and cotija cheese on top.
