To make this salad, start by preheating your oven to 425 F.
If using whole butternut squash, prepare the squash by removing the seeds and chopping it into 1/2 inch pieces. If you're using pre-cut butternut squash (which I recommend - it's so much easier!) you can skip this step.
Add the chopped butternut squash to a sheet pan. Then, chop the red onion and add it to the baking sheet.
Add the olive oil, a pinch of sea salt, and a pinch of ground black pepper, and toss the squash and onion until they're fully coated in both. Make sure they're both spread out into an even layer on the sheet pan.
Transfer the baking sheet into the oven for 20 minutes.
While the veggies are in the oven, prepare the sausage. Heat a pan, on the stove, over medium heat, and add in the sausage.
Use a spoon to break the sausage up well, then allow it to cook until browned. Once the sausage is cooked through, remove it from the heat and set it aside.
Then, prepare the dressing. Add all of the dressing ingredients (the olive oil, maple syrup, apple cider vinegar, dijon mustard, garlic, kosher salt, and ground black pepper) to a blender and blend until smooth and creamy.
Once the veggies are done, remove them from the oven.
Then, add the kale and cooked sausage to the sheet pan, along with 1/4 of the dressing, and toss until they're fully incorporated with the veggies.
Return the sheet pan to the oven and allow everything to cook together for 15 more minutes.
Once the salad is done, remove it from the oven and allow it to cool for 10 minutes before adding the feta cheese, dried cranberries, and chopped pistachios.
Finally, drizzle the remaining dressing on top and toss to fully combine. Serve immediately and enjoy!
