Step 1Preheat the oven to 200 °C/ 400 °F. Halve the spaghetti squash lenghtwise. Use the tip of a chef's knife to break through the skin in the middle part and push the blade down until it cuts through. Using a spoon, scoop out the seeds and discard or reserve for snacking (you can roast them). Brush the inside of each half with melted ghee (keep some ghee for cooking the chorizo) and season with salt.
Place the spaghetti squash in the oven and bake for 25-40 minutes (timing depends on the size of the squash). Check the doneness using a fork.
