In a large bowl, toss the halved Brussels sprouts with olive oil, salt, pepper, garlic powder, and onion powder until well-coated.
Spread the Brussels sprouts evenly on a baking sheet and roast in the preheated oven for 20-25 minutes, or until they are crisp-tender and caramelized, stirring halfway through.
While the Brussels sprouts roast, prepare the honey mustard dressing. In a small bowl, whisk together honey, Dijon mustard, apple cider vinegar, salt, and pepper until smooth.
Once the Brussels sprouts are done, remove them from the oven and let them cool slightly for about 5-10 minutes.
In a large serving bowl, combine the roasted Brussels sprouts, toasted walnuts, dried cranberries, and feta cheese.
Drizzle the honey mustard dressing over the salad and gently toss to combine, ensuring everything is coated.
Garnish with freshly chopped parsley before serving.
Notes
Feel free to add other toppings like avocado or bacon for extra flavor.
