Preheat your oven to 400 degrees F. Add the butternut squash cubes to a large mixing bowl alongside the seasoning. Gently toss to coat the butternut squash cubes with seasoning, then lay them on a lined baking sheet and roast for about 30 minutes until tender.
Place the roasted butternut squash cubes in a large salad mixing bowl. Add in the baby kale, apple, pomegranate seeds, feta cheese, and the toasted pepitas.
Prep your vinaigrette in a small mixing bowl by whisking together olive oil, vinegar, mustard, salt and pepper. Pour over your prepared salad and gently mix to combine. Enjoy your salad!
