2 tsp sugar (optional, but helps to caramelize the mushrooms)
1 tsp cumin
1 tsp oregano
Salt and pepper to taste
8 corn tortillas
Method
1
Preheat the oven to 425 degrees. Toss the chopped mushrooms with olive oil, lime juice, soy sauce, and spices until well coated.
2
Spread the mushrooms in a single layer on a baking sheet. Do not overcrowd the pans, use two baking sheets if needed.
3
Roast for 20 minutes. Stir the mushrooms and push them back into a single layer. Roast for an additional 10-15 minutes until browned and beginning to crisp on the edges. The exact cooking time will depend on the mushrooms and the size of the slices.
4
Assemble the tacos with warmed corn tortilla, roasted mushrooms, cabbage slaw, and any additional toppings.
