Place the kale leaves on a cutting board and chop them into strips, then place them in a bowl. Add 1 tablespoon of oil, the adobo sauce and chipotle chili powder, tossing well. Use your hands to massage the ingredients into the kale. Set it aside. (and wash your hands! so you don’t burn the heck out of your eyeballs.)
Heat a large skillet over medium-low heat and add the remaining 1 tablespoon of olive oil and butter. Stir in the mushrooms, tossing to coat in the butter, then cook until the mushrooms are soft and juicy, about 6 to 8 minutes. Stir in the garlic, cumin, salt and pepper. Stir in the chopped cilantro. Turn off the heat. I also like to crumble a bit of the queso fresco in here now too, but that’s your call.
Assemble the tacos by placing a handful of the marinated kale on a tortilla. Place the avocado slices on top, then some of the mushrooms, the tomatoes, sweet onion, more cilantro and queso fresco. Devour!
