Remove the chorizo from its casings and cook in a large skillet over medium heat for about 4 minutes. Use a slotted spoon to transfer the chorizo to a plate; leave the drippings in the pan.
Cook squash and aromatics:
Add the onion to the skillet and cook, stirring often, for about 3 minutes, until golden and soft. Add the squash, garlic powder, and cumin and continue to cook for 5 to 7 minutes, until the squash is soft.
Combine:
Add the kale and cook until wilted, about 2 minutes. Add the cooked chorizo back into the pan and stir to combine. Remove the pan from the heat, and the lime juice, and season with salt and pepper.
Assemble:
To assemble the tacos, place a layer of chorizo and squash mixture on each tortilla, top with some crumbled goat cheese, and sprinkle with cilantro.
Notes
Butternut squash: buy it pre-cubed or use fresh squash (if so, cube it and steam it quickly in the microwave until soft to cut the cooking time in half)
