Wash the sweet potatoes thoroughly and slice sweet potatoes into thick wedges. Place the sweet potatoes on a lined baking sheet and drizzle lightly with olive oil. Season with salt
Bake in the preheated oven for about 30-35 minutes, or until they are tender and golden brown. You can check for doneness by inserting a knife into the center; it should slide in easily.
While the sweet potatoes are baking, prepare the crumble mixture. In a mixing bowl, combine the chopped cashews, chopped dates, crumbled feta, arugula, orange zest, olive oil, and maple syrup. Mix well until everything is combined. Season with salt.
Once the sweet potatoes are done baking, remove them from the oven and place on a serving platter. Top the wedges with the crunchy crumble.
Serve warm, garnished with additional orange zest if desired. Enjoy!
